text: Worried: Alice Dreger attended the class at East Lansing High School after her son asked her to sit in on it so she could hear what was going on first hand . An outraged mom live tweeted her son's sex education class after becoming outraged by its abstinence only stance. Author Alice Dreger took to Twitter to express her horror at what she heard at East Lansing High School, in Michigan, when she sat in on a lesson earlier this week. Ms Dreger, a respected professor, began furiously tweeting out the contents of the lesson - which was filled with horror stories about what happened to people who have pre-marital sex. According to the 45 tweets sent by Ms Dreger during the lesson, stories included people who lost all their friends when they became pregnant, people who fell into comas for 11 years after taking drugs and high school dropouts. 'The whole lesson here is "sex is part of a terrible lifestyle. Drugs, unemployment, failure to finish school -- sex is part of the disaster",' tweeted Ms Dreger. She added: 'I feel like raising my hand and saying "Can I tell my sexual history, which involves a lot of pleasure before and during marriage?"' Ms Dreger also complained of the incorrect information being handed to the students, who are freshmen in high school, by the teacher, who did not normally work at the school. At one point, paper babies were handed around the class to show how 'easily' condoms fail: the teacher claimed they were ineffective one in six times. "We are going to roll this dice eight times,' Ms Dreger reported the teacher as saying. 'Every time your number comes up, in pretend your condom failed and you get a paper baby.' In fact, according to the NHS, just two in 100 women will get pregnant a year when people use condoms correctly. Outrage: Ms Dreger's tweets, above, show just how cross she got during the class earlier this week . Untrue: The school has denied it only teaches abstinence, saying it just happened to be that day's lesson . The tweets went viral, with people across the world getting involved with the debate over sex education. But the school has denied it only teaches abstinence - saying it was just that day's lecture which focused on the subject. 'Abstinence-based instruction teaches that abstinence is the only way to be completely safe, but the curriculum also reviews contraception choices. This parent attended on a day where abstinence was being taught,' high school principal Coby Fletcher said in the statement released to The Lansing State Journal. The school has taken no direct action against Ms Dreger for the tweets. They have, however, banned her from the premises - apart from her son's events - for swearing at the end of the lesson. @alicedreger: The kid has invited me to his health class on sex ed to see how bad it is, so I'm going. But hands over my mouth means I can't live-tweet it . @alicedreger: Uh oh. They stuck me in the corner with my computer and there is wifi....so I can live tweet this. We still pledge loyalty to the flag, huh? @alicedreger: I can't stand this. They're teaching "abstinence stories" that worked and non-abstinence" stories that "led to consequences." @alicedreger: The visitor-teacher is telling my kid abstinence education reduces premarital sex. My kid is trying to show her studies that dispute that. @alicedreger: She's being completely condescending. "You can look up anything on the internet" Then refers him to site on abstinence education! @alicedreger: I feel like raising my hand and saying "Can I tell my sexual history, which involves a lot of pleasure before and during marriage?" @alicedreger: And how I've had a lot of lovers and have never gotten pregnant by accident? Yes, I had HPV! And I would get the vaccine! @alicedreger: In fact I have had the vaccine! @alicedreger: Now we're hearing a horror story about marijuana use. @alicedreger: The regular health teacher in trying to shut my kid up referred to "LGBYT." And how the board decides what we learn. @alicedreger: The guy telling the "abstinence" story is now telling us about having sex as a teenager. I'm confused. @alicedreger: Now he's talking about getting a girl preg and them hiding it from their parents. Yup, that's what sexual shame does, dude! @alicedreger: Preg girl got picked on so her friends desserted her. That's what happens if you have sex, kids! Yup! Pregnant and NO FRIENDS! @alicedreger: He and the girl both had alcoholic fathers. But somehow he's not recommending never drinking. @alicedreger: The whole lesson here is "sex is part of a terrible lifestyle. Drugs, unemployment, failure to finish school -- sex is part of the disaster" @alicedreger: This guy really thinks this story of "I f***** up for years and years" is going to lead to other kids not f**** up. @alicedreger: Whereas the lesson I would take is "sometimes it takes years to get your s*** together, and that's okay"? @alicedreger: Oh and of course, now a story about a friend who OD'ed and "was a vegetable 11 years. Tore their family apart." FFS. Welcome to sex ed. @alicedreger: This whole story of OD's, people in prison, out-of-marriage pregnancies is ironically a story of this guy's resilience and normalcy. @alicedreger: "I have a daughter whose 21 and I would go absolutely nuts if I knew she ever let a stranger into her house." @alicedreger: "I finally met a great girl who was brought up in abstinence, and her life was so much better. I put her on a pedestal above everyone else." @alicedreger: "I liked her so much [I so wanted to **** her] I decided to change my lifestyle and go with abstinence [until I could F*** her]." @alicedreger: "Two years after we started dating I asked her to marry me and we're 8 years married." And I'll bet yer f****, aren't ya! @alicedreger: "We're not saying having sex is a bad thing. My story I can say having sex was a bad thing for me because I craved it." @alicedreger: "You'll find a good girl. If you find one that says 'no,' that's the one you want." HE ACTUALLY JUST SAID THAT. @alicedreger: "We can look up things on the internet but until you live that lifestyle you won't see it the same." The whole talk is "lifestyle." @alicedreger: Now the woman is up. "Sometimes condoms fail." @alicedreger: She says "it is absolutely better to use something than nothing" in terms of birth control. "But it can fail." @alicedreger: "It takes only 1 sperm to fertilize an egg. It takes only 1 time having sex to get pregnant." Yet she's not suggesting oral or a***. @alicedreger: She's now telling story of condom box in which EVERY SINGLE CONDOM HAD A HOLE. @alicedreger: She says per the FDA 1 out of every 400 boxes of condom can be totally defective. "You might get that 400th box." BE AFRAID! @alicedreger: About 18% chance a condom will fail, she says. @alicedreger: "On average 1 out of 6 times there is a mishap with a condom." "Every day in US 1600+ teen pregnancies." Lesson: condoms fail? WTF? @alicedreger: Condoms. They fail. You get pregnant. Your friends leave you. You drop out of school. Your kids end up in the army. @alicedreger: "We are going to roll this dice 8 times. Every time your number comes up, in pretend your condom failed and you get a paper baby." J****!!! @alicedreger: Paper babies are being handed out to EVERYONE. They have ALL HAD CONDOM FAILURE AND THE WHOLE CLASS IS PREGNANT. @alicedreger: "You have to have a baby!" There are apparently no scissors in the room for paper abortions. @alicedreger: "I'm going to collect the babies that you don't want. We recycle them." @alicedreger: "Safe sex is kind of a misnomer." @alicedreger: It's over. I need a drink. @alicedreger: I can't get up. I'm too stunned.
