Why are so many subreddits dedicated to hobbies so cruel when you post something you worked hard on?

Not gonna name any names but it feels like it happens to me a lot, get all deep in special interest and post something I'm proud of just for all the comments to be like this is terrible or why does this feel AI generated? like damn bro why encourage people to get into your hobby when you can just make them feel like shit for trying.

Luckily I have real friends that support my interests but I think I'm done trying to meet new people with the same interests. I'll stick to my five friends. Sucks but I guess that's just how the Internet has always been, reddit in particular, male dominated fields even moreso
