does saying "from the river to the sea, Palestine will be free" constitute antisemitism? Or "Israel is an apartheid state"? or "American politicians continue to support Israel because they are getting paid off"?
I don't think any of that does but I completely understand others saying those statements either are directly or they endanger Jewish people. for people who think this, what I wrote above is crap. you can keep it off your server but defederating a server for it goes too far imo.
@mray
now if somebody was clearly pro Israel and Jewish and somebody else posted what I wrote in replies to them once or twice during a conversation on the issues, that's probably not harassment. doing it relentlessly, esp if the replied to says they consider in antisemitic, clearly is. or doing it at random times. I'd argue the person should silence/block them or maybe eventually their server should. but only block their server if this is happening a lot from multiple accounts there.
