Yes, I mean globally recognized religions with millions of followers. Sorry but I'd rather not delve deeper into this. While I initiated this thread, I don't want it to escalate into a flame war or offend sincere individuals who are faultless and have good intentions.
No flame war, no offence. I was guessing who you meant and if I'm right that is a sect, with millions of members, but still a sect. That's all. Sorry, just being my pedantic self.
As someone raised in a major religion who opted out, I can confirm that I quickly became an outside to my religious community. I don't feel it was much of a loss though. The only reason I knew those people was church.
This is probably less common with people who go to church in holidays only. The devout are different.
