In my political opinion Israel is an artificially created state which is why it's so unstable and we should simply walk away and cut our losses on this. I believe my opinion is the prevailing populist opinion too so y'all have to contend with that.
There needs to be some compromise between our points of view or else we'll continue to get more war and violence. I think our country needs to recognize our responsibility for this mess and should offer land in North America of equivalent value for any Zionist refugees and then leave the poor people of that land alone. I ultra extremists would feel right at home in the Catskills lol.
Certainly some is antisemitism. To imply, as you have, that there is 0% legitimacy to any other reasons to hate the behavior of the current Israeli government is just as pro-genocide as you claim antisemitism.
Most people I know who oppose Israel's actions in Gaza have no problem with Jewish people; many themselves are Jewish.
