The Israeli-Palestinian conflict is one of the more interesting political topics in the US, because supporters of each are not clearly divided along political lines like other issues. The Right generally supports Israel, but the far Right and alt-Right often hold anti-Semitic views, so many on the far Right are anti-Israel. But those same people also hate Muslims. On the other hand, a lot of the Left is pro-Palestine, but also pro-Jew. And they're pro-Jew and pro-Muslim, who often hate each other, especially in the Middle East. Then you've got a far Left board like Era that is pro-Palestine, but they're not allowed to use Nazi comparisons because that would be inflammatory against Jews, who are historically some of the ultimate victims.
It's just this hodgepodge of allegiances and prejudices that melts into a big pot of cognitive dissonance, for most of the people with the most passionate views.
