If another nation came into my nations city and launched missiles, raped and captured women and children, and killed thousands I would hope my nation wouldn’t take that lying down. On top of that they use the citizens as human shields? Yes innocent Palestinians are dying but so did innocent Israelites. This isn’t a war that is easily understood because the enemy disguises themselves as normal people and uses their fellow country man as their shield.
The only literal nazis I’ve ever seen are all right wing nut jobs. The only time I’ve ever heard the antisemitic tropes about Jews owning banks and space lasers and shit is from right wing nut jobs.
I’ve only heard left wing nut jobs say things like ‘palestine has the right to exist’ and ‘the Israeli government is comitting [genocide|ethnic cleansing] in palestine.’ But I’ve not heard anything actually antisemitic.
That’s because it’s 110% a bad-faith argument. They couldn’t care less about anti-semitism in the sense of disliking Jewish people (as you pointed out), but they recognize the term as a convenient weapon to toss at anyone who might criticize Israel.
It’s a weird bit of mental gymnastics.
