I wonder if things like the Freedom From Religion Foundation would qualify for a ban. Or a church that preaches that their god is the correct one.
You can't choose your age, gender (mostly), race, caste, sexual orientation, or veteran status, but religion is malleable and public discourse about those topics where one person argues that their view is superior to others is pretty important to society.
It's not clear if YouTube is going to remove anything that asserts some religious beliefs are indeed superior to others.
