Non-Religion is cool if you get used to it. 91% of all Germans are "Not practising any religion". On paper some 70% still are members of religious communities but otherwise we don't give a fuck and instead going to church we meet for beer and bretzel breakfast on sunday. We stopped being religious after two World Wars as God was never on our side. Now we ain't on his side either. Never been more happy.
Funny thing, officially Religion is part of school. But from what I remember it was more a history lesson. I remember every jewish and muslim holiday but not a single Christian Martyrer. Yes, around half of religious lessons at school was about other religions. Most likely because of selective memory - on holidays I could have beer and bretzel breakfast. Martyrers don't feed me.
Because it worked to well in Zimbabwe, Sowjetunion 1, Sowjetunion 2, China, and many more
