I reject your original false premise that "so many" are actually doing this.
I have faith that pro-Palestinian folks are on the whole, rational and empathetic enough to know that trump will end the comfort, and even lives, of so many groups of vulnerable people, decidedly inclusive of the Palestinians there. We elect Harris today so that our democracy lives another day. That preserves our rights to fill the streets in protest and interrupt commerce until Israel's genocide ends WHEN Kamala actually has the power to stop it, after being sworn in.
Until then, we stay vocal and we place the pressure to end this where it firmly belongs - Netanyahu and the Israelis instigating and enabling this historically horrible thing.
