Sorry, but they often simply ask for that. 

Like for example, you are vegan (maybe, it is example), I have no problem with you. You do problems to me, I start to have problem with you. It is this simple. The fact you are vegan is of no importance. 

So you see, we are not against vegans. We are against assholes.

Very well put. I see some vegans the way I see proselytizers, that they force their world view on others.
