It would be an interesting psycho-sociological exercise to try and understand what attracts people to extreme sects like this.  Given their prominence in the USA this is not a phenomenon to be taken lightly.

I am intrigued by the weird connections - authoritarianism, anti-Semitism, pro-Zionism,  royalism, ritualism, sexual repression, holocaust denial, climate change denial, creationism, homophobia, conspiracy theories, millenarianism, extreme dualities of good and evil...

There is a whole psychology here which progressives need to understand if they wish to counter it.
