I don't accept that I have a moral obligation to ignore reality (or worse, deny it).
It's a matter of how you define "control" and "Jews", I suppose. "Jews" as in "all jewish people"? Obviously not. "Control" as in "total control over all media companies" also obviously not.
Individual Jews in powerful positions of plenty of powerful companies at disproportionate rates? Probably yes, at least for the US, less so in Europe for obvious reasons.
In the end, I guess Facebook should simply outlaw all blanket statements. None of them are true, all of them are oversimplifying complex issues and are, if believed, harmful. But then again, what would remain if they did so?
I have personally ancestors that died during the Shoah so I am especially sensible to the damage antisemitism can do but it’s getting downright absurd at this point
Edit: more precisely I do not believe that censoring such speeches can do any good. If the content of the speech is false there will be reactance and a Streisand like effect and if’s true it will only lead to more comptent and resentment.
