Just to throw my opinion in- I try not to actively alienate anyone. At the same time, If I hear something I don't agree with I'm going to object to it, argue against it or ridicule it most of the time and if people feel alienated because of my honest responses tough luck. Also if someone says something that actually makes me want to punch them I'll probably avoid them so as to make sure that doesn't actually happen.

Also you can value art without valuing the artist but that might end with you paying royalties to a complete wanker who'll spend them on bigoted electoral campaigns etc... And I still wouldn't want social interaction with someone who makes me want to punch them every few minutes.
