My grandfather believed in a Hildegard von Bingen based religion that got him convinced putting rocks under his pillow and following a strict monotonous diet would be good for his health. He died.

“Men will continue to commit atrocities as long as they continue to believe absurdities.” ―Voltaire

All religion should be a thing of the past. If banning something is the best course of action I don't know, but currently it would be something I'd vote yes to if I could; unless someone convinces me otherwise without using ad hominems, nonsensical claims such as being racist, or any other fallacies. I simply despise anything that makes humanity dumber.

To consider antireligion instead of atheism
“The harm of religion is historically evident whereas the presence or absence of gods is not. Ultimately, the continued existence of religion is predicated on the indoctrination of children and suppression of rational thought. Therefore, I am against religion but not necessarily against the idea of gods. For all we know gods are computer scientists and we are in their video game.” ―https://www.arscyni.cc/file/antireligion.html
