Being able to laugh at something doesn’t mean there’s a joke. Laughing at something doesn’t mean there’s humor.
This is the problem. It’s not a matter of people liking fucked up things, it’s just that it isn’t funny.
If you liked things that tasted bad, and you said they tasted good, just because you like something doesn’t mean it’s good. Especially when you like things that you recognize as tasty bad.
Liking something doesn’t make it good, laughing at something doesn’t make it funny, and saying “people like different things” doesn’t mean I’m wrong about edgy humor rarely being actually humorous.
