I do too, but lately I've even been a bit muted. I tend to go off on the social vs. fiscal/economic conservative threads though.
Fun stuff!
I keep saying whatever I want. I try to be polite and non-combative. I don't reply to or try to argue witheveryone who disagrees with me.
But occasionally, someone will call me a name or tell me how dumb I am. When that happens, I give as I get or even worse. Once in a while I feel bad about it later, but often I feel quite good!
