Reminds me of the Barelvi guy who told me that "the Quran" says that at the end of time that "we" (Muslims and Christians) will face off against the Jews and the Dajjal. I felt obligated to say I'm Jewish, but refrained from saying that his source was a weak Hadith. He also messed up al-Fatihah.

I can sympathize in part (my Hebrew is not exactly functional), but I can't really justify the image of being the perfidious Jew when the other party is making errors that are that basic.
