Have you heard that the ACLU is quite frequently referred to as the Anti Christian League for their actions in removing crosses and ten-commandments and other actions?  This is where I dislike them so much.  They do not always support First Amendment Rights when it comes to conservative Christians.  They, like most liberal organizations, are only tolerant to people of their own kind and beliefs.   Here is your test of Free Speech.  If you support the KKK's right to hold a parade without a protest, then you truly support Free Speech.    
Also remember,  for some conservatives,  this is their daily life.  Remember that they have to put up with the barbs, the insults, and put-downs that you claim to be against.  Most do not insist that the people insulting them shut up or say that the insulters should not be allowed to voice their opinions.
