Mondoweiss is a blog that most Jewish people balk at, and is generally regarded as a hate site. It often veers into outright antisemitism and support for terrorists, including publishing antisemitic cartoons. Its whole raison d'etre is to destabilise the mainstream diaspora Jewish community. Yes, I know the blogger is Jewish. But if you think that gives credence to him (or your argument) then you know absolutely nothing about Judaism and Jewish beliefs.
So pick your sources more wisely. If posters were repeatedly posting links to sites that host highly iffy commentary about Muslims and Islam because it suited their narrative, and a Muslim poster pointed out how problematic that was, what would your response be? Would you just arrogantly tell them they're wrong and carry on regardless? Or would you, rightly, report the thread for platforming anti-Muslim racism.
Talking of which, this thread is revolting. A bunch of non-Jewish posters arrogantly dissecting us, yet showing a complete lack of understanding of Jewish people and Zionism. And basically just listing Jews (well the good ones by OP's definition - she's even got post upthread linking to a list of good Jews. Lists of Jews is somewhere we've been before incidentally, it makes my stomach turn).
Antisemitic tropes are openly being shared right now, with discredited Historians like David Irving trending again.
Antisemitic websites, blogs and social media that openly share antisemitic tropes have been shared repeatedly on this thread and other similar threads. Some link to notorious conspiracy theory media - I mean the Mint Press FFS! And this is where left and right comes into play. Antisemitic tropes have been as openly shared by the left as they are on the right, where holocaust denier David Irving sits. On the other extreme, Roger Waters has been dabbling in holocaust revisionism and inversion for years, and now open 7/10 denial - counts himself as left wing. It's incredible how some people on here will only acknowledge antisemitic hatred once they've checked what end of the political spectrum it comes from. I'm sure you'll claim you don't care about left and right and don't check, but it's just way too much of a coincidence that the only Jew-hatred that gets acknowledged on here by many posters only comes from the right.
