This really shouldn’t be surprising. The man has signalled and announced his desire to shoot first and ask questions later at the slightest provocation. He’s also very vocally pro-Israel. Anybody crowing about “Genocide Joe” is a bad actor intentionally trying to confuse the discourse with bullshit noise. There is no ethical vote except for Biden. Every single US president has been pro-Israel, so just drop that argument and start focussing on how to materially improve living conditions of actual Americans.
