By this logic Chinese, Japanese, Classical Vietnamese and Classical Korean are all sorta kinda just Chinese.
Aside from being amazingly ignorant ( it can be argued Chinese dialects alone are more diverse than Romance languages) your not going to be able to have a Cantonese speaker moderate a Japanese forum.
That said, why are we realistically expecting Facebook to be able to do all this. The moderation should really occur in your head, if you're reading really hateful things online, maybe stop reading them. It turns into an endless game of whack-a-mole.
There are tons of Reddit threads I've been in where I felt I was being personally attacked, or reading pure hate speech. I stopped using Reddit because it wasn't good for me. To be completely fair to Facebook it's not even possible to moderate their platform to the extent this article imagines.
I think a fair compromise would be to allow Nations to ban or heavily restrict Facebook. And Facebook should comply with that. Hell, a Facebook timeout for all of humanity wouldn't be a bad idea.
Maybe given the week of an election just shut the whole thing down aside from messenger.
