There is no genocide happening. War is an ugly thing. Kamala isn't going to change US policy toward Israel because there are no good options. If there were, Biden would have taken them already.
The ICC and ICJ heard evidence of both sides and ruled that yes it’s happening. The Israeli government is boldly bragging about it, with Netanyahu bragging in speeches that there won’t be a Palestinian state as long as he’s in power, and his cabinet members are openly talking about eliminating Palestine and forcibly evicting millions of Palestinians into Jordan.
Granted, centrists do suggest that anyone who isn't on board with the Bidenyahu genocide is a Trump supporter, but that's just because their wholehearted support for the genocide is indefensible.
