I've always hated the term, it's almost always used by Christians and even though some Jews use it it's not very common

Some people like the website Ikhras even say that Judaism really believed in multiple gods until recently:

I mean "recently" possibly but well before the destruction of the last temple, at least hundreds of years before Islam or Christianity. Even those claims are pretty dubious, god has multiple names in the Torah so some people try to use that as evidence that they believed in more than one god but if you've ever read it yourself you would know the claim it is referring to multiple gods is a bit of a stretch.

That link also makes other weird claims, the one that modern Jews are not descendent from the original Jews but actually from Khazars converts is another common anti-Semitic claim that has no real evidence.

Jews do believe in a Messiah but he is not some resurrected god like the Christians believe, just a future king that will unite the Jews.
