Summarize the following:
People who are not transgender or nonbinary are called "cisgender." Being cisgender means you rarely have to worry that people will mistake you for a gender that feels wrong. It means you are unlikely to experience familial rejection, unemployment, social isolation, or physical violence because of your gender identity. While some transgender people do not experience any of these problems, many do.  Transgender people are at an outsize risk of physical violence from others.  Due to physical attacks and familial rejection, transgender people experience high rates of suicide attempts.  Recognize that being cisgender means that you avoid a lot of issues that transgender people have no choice but to face. Be a good ally and stand up for transgender people. If you hear someone putting down someone in your life, speak up and say that you respect that person and don't want to hear them insulted. If someone uses a slur or makes a joke or a prejudicial statement about gender-nonconforming people, tell them you are offended. You might say, "I don't appreciate you calling my friend a "tr*nny." You don't know what her life is. You should check yourself before you start putting down people based on their gender." Your time and money can help improve the quality of life of the transgender people you know and the ones you haven't met.  Transgender youth experience high rates of homelessness due to familial abandonment or hostility. Consider donating to a shelter for LGBTQ youth. Advocate for better treatment of transgender prisoners, who are sometimes placed in the wrong facility based on their assigned sex. Support affordable healthcare for gender-affirming surgery, hormones, trans-friendly gynecology, and other treatments essential to the wellbeing of some transgender people.

Summary:
Recognize cisgender privilege. Speak up if you hear transphobic statements. Donate to or volunteer with trans-positive causes.
