Why? Let them live in their own little world and enjoy their narrow-mindedness.
Get out of there to save yourself heartache and pain and join communities where you have fun and enjoy the people.
I love my shipping communities and my Genshin-simps and my hentai lovers and my anime-enthusiasts. If there is a post I do not like, I ignore it. Happy are those who can look at the things they enjoy and concentrate on them instead of getting hung up on people who throw s**t on something they have no idea of. If I meet somebody like that in real life I can do my share and get into a discussion about why they do not like it and try to change their opinion. But until then they are nameless, faceless people on the internet I do not care to spend time with.
Do something good for your sanity and stay far away from there. 😉
