I completely do not understand religious people. Like, people believe and dedicate their lives to some entity that they have never seen and have no proof exists. In fact, there is a lot of proof things are done NOT by that entity, yet they still choose to believe it. Why? What is the reasoning?? And then they attack others who believe in a different entity or none at all! From an objective standpoint, it’s complete delusion!
@WahPlus amen (no pun intended)
Hypertextism 
@WahPlus Most probably comes from childhood, culture or region.
As someone with heavy religious history, beliefs like that of Christianity or Satanism can form from culture or childhood, maybe due to parents.
I wouldn't label it "delusion" but just people living their lives with a different mindset.
Communities attacking opposing communities is very uncommon but never super rare; It normally isn't the entire community but only the people who are there only to cater.
