You described almost every religion ever.
Religion is a mental disorder. Prove me wrong. (with actual studies and not anecdotes)
In order to answer the challenge, I suppose the first question would be ‘what constitutes a religion?’ If you’re simply talking about a group of people who share a passionately held belief that tries to get others to conform to that belief through emotional manipulation, intimidation and peer pressure, well….you’re pretty much talking about the entire human race.
