Luther had a good reason to hate the Jewish religion. He quoted favorably from Jewish converts in the book. Orthodox Jews typically take any criticism of their religion as proof of insane hatred against all Jews. And they tend to blame their own misbehavior, even when the misbehavior is commanded by their Rabbis in the Talmud, on the paranoia and unexplained anti-semitism of the Gentiles.
So we’ll write off a major religion (and its people?) because of some fantastical parts of Talmud and a few dunderheads in Israel. Got it.
