Only the super-dedicated ones.

I knew a guy in highschool, he was adopted from Russia by a Russian-Jewish family. He was raised Jewish. Somewhere after highschool he got dragged into dark spots of the internet. Him and a close friend of his converted to Eastern Orthodox and began dropping constant Nazi dog whistles. Explicit anti-semitism. Both were in the military, one was an Army Ranger. Their posts were reported to LE but nothing came of it.

I'm confident the Ranger would kill for fun if given the chance, and any evidence of his war crimes would be covered up.

Knew a totally different Orthodox convert. He converted in college, went to school for political science. Sucked on his cross necklace and told my sister she'd be going to hell. She thankfully broke up with him.

The Orthodox church attracts some real cretins in my experience.
