You’re clearly very naive and cannot see the world as more than black and white. Now the Israeli state are the bad guys and the Palestinians are the good guys. So now it is OK to boycott jews again, shout about the eradication of the Jewish state and its people (“from the river to the sea”) and talk about a one-directional genocide since “75 years and 182 days”. This is either really really stupid or blatantly antisemitic.

They said that advocating for the eradication of the Jewish state and it's people is either stupid or antisemitic. If you aren't advocating that (and I don't have any particular reason to think you are) then that statement doesn't even apply to you. It's a straw man argument. But looking at the link you posted, there's a "river to the sea" comment right there from someone else. So I can see where they might have gotten that impression. Seems to me we can chalk this up to a simple misunderstanding. They made bad faith assumptions about you, you made bad faith assumptions against them. Lets move on.
