FP's are proselytary because their religious worldview compels them to be so. While not proselytizers for Judaism, Jews are nevertheless commanded to "compel" the nations of the world to accept the Noachide Laws. This is hardly z*r*astrian "tolerance." And as I said, if you want "tolerance," take up polytheism. "Tolerant monotheism" is a contradiction in terms.
I was just pointing out why some Jews might not want to ‘get involved’ with those they consider idolatrous.
