Here is an interesting lecture given by a Jewish Rabbi, that speaks of the missionary threat posed to Judaism, as many may (not) be aware of, many Jews face the same problems Muslims do when it comes to missionaries and their attempts of evangelising. Missionaries use the same tactics they use on Muslims, onto Jews, looking for any gullible folk amongst both parties, and to begin twisting both scriptures in order to trick the Muslim and Jew into the evangelical mindset.
