First of all, why the fuck would all names for people be equal? That’s insane. Do you think that the n word is equally offensive as those slurs you listed too? Or you just think it’s fine like calling someone Frenchie? Either way doesn’t look good.
Secondly this shit is so established there’s a Wikipedia page about it. Just cos you haven’t heard of it doesn’t mean it’s just being made up, there’s no need to go on some anti-woke crusade.
