What are some notable scams in history that went unnoticed for so long?

tried to fucking brainwash and indoctrinate people straight from birth.

Great, so teaching kids what the parents believe is brainwashing now? Yep. Anything you learn when you are born is brainwashing. That's right.

Ok, I'm just kidding. I get what you're trying to say. Religion demands that you believe everything your parents taught you. The thing is, Islam commands this (first line of Islamic Laws by Ayatollah Sistani):

"A Muslim’s belief in the fundamentals of religion (uṣūl al‑dīn) must be based on personal insight [i.e. grounded in reason], and he cannot follow anyone in the fundamentals of religion; i.e. he cannot accept the word of someone who knows about the fundamentals of religion simply because that person says so. "

Generally be incredibly two-faced

Yep, too many 'saints' use Islam to defend their actions. It's sad really.

Not exactly. Switched to lemmy from reddit, first thing that came up 🤷
