I try, as best as possible, to reflect the opinions of whomever I happen to be talking to at the time (fortunately I rarely get put in a position where I have to discuss politics) - ie I'm very measured and moderately supportive (although not to the extent where my comments are memorable) when I'm around friends who are involved in campus liberation stuff (anti-sexism and Pride and the like), whereas when I'm with friends from my home town I'm comfortably (although again, not excessively) on the casual bigotry banterbus.
Very good.
I myself ran into a spot of trouble on Friday night when a few friends stopped by and one srat chick I don't know that well started talking politics. Having already begun drinking, I was reasonably distraught that someone would wish to take me from my happy place to even talk about Donald Trump outside the sarcastic. This resulted in an "exchange of ideas" where I exposed my neo-fascistic/Stalinist sentiments to those assembled; at least one person was there who I'd rather have not know my actual viewpoints. Still a bit angry at myself for this.
Haha, of course, it's always problematic when you combine drinking and being around people who have strong political opinions - if I ever do say anything slightly off-colour I just pin on the alcohol or say it was humour.
