Do you write screeds about the woke mob and women with blue hair too?
It’s not normal, you’re completely right about that. It doesn’t matter. Everything does not have to look like the corporate internet and frankly advocating that everything on the internet wear a suit and tie to be “taken serious” (your words) is something you should re-examine. Spaces with different cultures are good and having a kneejerk reactionary intolerance to them is bad.
