But do you tip generously?

"They're nice when they're not mean." is a pretty bad take.

They're only perceived as incredibly violent by religious old people... Death metal (and most other heavy music) fans are generally seen as nice people, because it's true and has ever only been so. Same goes for horror movie nuts etc.

I actually find it odd to see a comment like yours here, it's such a well known thing that religious, conservative and mostly old people get bent out of shape and make a huge fuss about any new and/or, from their view, extreme thing. It's been the same for centuries. Before death metal they said the same about metal, before that it was rock, hip hop, pop music, jazz etc. Same with how every new generation is seen as lazy, disrespectful, dumb etc. which we have texts about from thousands of years ago.

As said, I'm very surprised to see a comment like yours here. And it seems like you think you have a liberal (in the word definition meaning, not the current political one) and/or at least open minded view, but it's actually not that at all. My 80yo grandmother has a more truthful and accepting view than what you seem to have. I do think you were partially very clumsy with your words though, at least I hope so, but even with that in mind it's still surprising to see a view like this from someone in any place like here.
