@Voland's right hand Re: How about some balance?
Wow.
Even your response could be viewed as being antisemitic. Free clue. Judaism is both a race and a religion. Prior to the second world war, the largest Jewish community in Europe was in Poland with communities over 400 years old before the Holocaust.
The issue though is that its possible to search for specific key words or phrases which can give clues to people belonging to hate groups. "88" for example. And then the BDS movement which is not only misguided but also produces antisemitic rhetoric and hate speech.
The underlying issue is that Facebook does have the ability to control hate speech as well as other user content, yet here is an area where they are turning a 'blind eye'. This would be akin to the 'pink sheet' contracts that were afforded spammers by the ISPs and Telcos.
Antisemitism isn't getting all of the outrage.
There's more, but I doubt you'd grok it.
