Reading it back I agree that it seems snobbish, and I'm sorry for that. I'm tired of bending over backwards to accommodate objectively poor behaviour though. Sometimes you just have to say "this is not for you".
If we go into that with a kind heart (and not just to elevate ourselves above others), it can be a good thing. Admitting unfashionable truths lets us move on to situations where more people are happy.
For my part, I'm more than happy to admit when something is not for me — be that due to a lack of intelligence, interest, or motivation — and I'm happier for it.
