If you believe you need to commit genocide to live, you're a fascist that should not physically be allowed to continue to exist. Period.
There is nothing worse than commiting a genocide, because the genocide never stops at the intended target.
The US and Israel started with Palestinians and now are expanding to all arabs. They have escalated once. They will escalate again. There is no less genocide or more genocide. There is just genocide. Either you support it, in which case see the first sentence, or you're not voting for it.
It doesn't matter if you believe it. I'm entirely sure, in fact I know for a fact, there were Nazis that solely supported the economic rhetoric of the party.
They were exactly as responsible as every other Nazi.
