Jews in general don't actively seek out converts. Islam is such a feared minority in these parts (the West) that any attempt at spreading the religion would likely be labeled extremism or terrorism despite the fact that most Muslims, as with Christians, are actually peaceful, decent people. If you were in the Middle East, however, you'd have plenty of conservative Muslims telling you you're going to hell. Or you'd be killed for being an infidel, depending on where you are.
