This is so me. I am very opinionated and get into fights with people on facebook all the time, but I feel embarassed because in person I am not like that, I have social anxiety so I would never say most of the things I do online lol. One thing I am particularly ashamed of is calling one of my dad's best friends a racist piece of **** on a facebook discussion group. Thankfully I don't think my dad knows about it and the few times I have had to be in the same house as his friend we ignore each other and pretend it never happened. Racism is just one of those things that really gets me going.
