I'm not them, for the record. But personally, I turned browser spellcheck off years ago; I have a lot of fantasy/scifi hobbies, and it often highlighted words that are correct but not in a dictionary, which was annoying, so I just shut it off. And also because it doesn't really matter, from a linguistic point of view; the purpose of language is to be understood, so as long as a typo doesn't detract from my meaning, I don't care. It'd be different if I was writing a business email, but I'm not, I'm shitposting on reddit, so who gives a fuck?
