The post was bloviating nonsense, a long-winded way of letting us know that he's firmly pro ethnic cleansing because "people have to pick sides". The idea that you have to either support the expulsion of all Jews from Israel or support a Jewish ethno-state is straight up bullshit. It's actually just completely baby-brained shitposting. There's a whole bunch of mental gymnastics and convenient blind spots you have to set up for yourself to be pro-Israel as it is: an ethno-apartheid state, rather than Israel as it should be: the genuine bastion of democracy they claim to be but actually aren't even close to and never have been in reality.
I place myself in the latter category of being "pro-Israel". I firmly believe it should and can exist as a true haven for both Palestinians and Israelis.
It also isn't helpful to pretend they just hate each other and that's that. Palestinians, for the most part, learn to hate Israelis. Israelis, for the most part, are taught to hate Palestinians. It is a subtle but profound difference. It's a plain and simple lie that they hate each other because of each other's immutable characteristics.
