do you think you'd care of what helped or didn't help your cause?

I mean I hope I would, but also that has nothing to do with what I said. The fact that Palestinian antisemitism is rooted in their legitimate anger against their oppressors doesn't make it any less antisemitic.

And as a matter of fact, there is nothing a Palestinian can do to help the Palestinian cause.

That is completely false. October 7th (and the predictably genocidal backlash to it) essentially expanded the Palestinian solidarity movement by an order of magnitude, and before that the Second Intifada caused Israel to withdraw from Gaza and the First Intifada and the Second Intifada lead to Israel making concessions to Palestinians for the first time ever (the Oslo Accords, as much of a half-measure as they were). Moving away from violent resistance, BDS keeps expanding year after year, costing Israel billions of dollars (though admittedly this is more limited than most of us would like).
