“Nazism had an adverse affect on health outcomes” might be a bit of an understatement.

A couple other points: the NOI is much smaller in membership than many people think, at 50,000 members.

Much of this rank-and-file is relatively boring people with strange beliefs, which could be said about many religious people.

While anti-whiteness and antisemitism is purportedly a “core belief” of the NOI, Mainstream Christian denominations defended slavery and segregation, and antisemitism was a core belief of Catholicism at least until Vatican II, and many Protestant and Evangelical denominations maintain a supercessionist theology (that the New Testament fully and universally replaced the commandments of the Torah) which is itself a religious form of antisemitism.

Everyone who has ever mentioned meeting James Watson has him immediately saying something incredibly racist, sexist, or antisemitic.
