You could easily reword your comment as wishing there were convenience stores without the magazines.

I agree with the other person here. It’s just the context of YouTube. Take HN for example: there’s little to no adult content on this site.

I’m in a similar camp in that I’m frustrated daily that Facebook can’t figure out that I (admittedly a single 30 male) don’t want the lewd content. I say “show less of this” on every lewd post, but it can’t figure it out.

That being said, I think the answer is fostering/finding other communities with different natures rather than changing Facebook or YouTube to be something they aren’t.
