Since Jews can refer to people who's religion is Judaism, I'm not sure it is racist. He'd have to specifically target people based on origin to be racist.
Yes Jews (like Druze / Yazidi people) are an ethno-religious group - but do you think Kanye is targeting them based upon their religious beliefs, as if there’s some controversial aspect of Judaism that he doesn’t agree with? This seems far fetched.
Likely the latter, being that there are many misunderstood components of the Torah and other teachings and no shortage of ultra-orthodox rabbis willing to say crazy things. Almost every popular Hollywood comedy also makes some Jewish reference and joke by a Jewish actor because it is known.
Kanye is complaining about being uncomfortable with music producers based upon their being Jewish and saying he’s ”death con 5 (sic) on Jews”.
Kanye’s not discussing ultra orthodox habits or genital mutilation or any other aspect of religion. From what we’ve seen, nobody was discussing religion, it’s just racism.
It's a result of antisemitism - Jews weren't allowed to participate in most trades (or have building on streets for example, like here in London), so money lending was one of the few roles available. I've never heard religious teaching barring Jewish people from other trades.
And people that think Christians are lying hypocrites are anti-Christian. I'm not sure why people want the word antisemitism to have special treatment vs disdain for any other religion.
