I think you're underestimating human heterogeneity. The fix for this is to meet many different people, not engage in the kind of behavior you hate, and not bother hanging out with anyone who is put off after you learn that they were put off. You are not overwhelmingly likely to run out of people unless you live in the middle of nowhere. (Do you?)

I strongly second this. The people who are like you and who you would like most likely also hate the behaviors you don't want to engage in. By not engaging in them, you may alienate the people you dislike, but you'll make yourself more interesting to the people you actually do want to hang out with.
