People of religion, aren't most religions fraud and false?

Gee, you really have me thinkin', man.
All them years in preachin' school for nothin'

Most religions are not fraudulent, because they contain people who actually, genuinely, believe the tenets of their religion.
However, this does not say anything about their objective truth. Logically, if two religions say opposite things only one of them can be true. If there are a list of statements of belief, these statements are either true or false. It wouldn't take many such statements to get it down to one religion being the maximum that could be correct.
However, I do not understand why you have asked people of religion, this is simply a matter of maths and logic.

Edit: the only way someone could know that they were correct in their beliefs is to look at the central tenets, and see if they stand up historically and logically. Even if someone knows God personally, there may be some aspects of belief you have accepted that don't stand up; but knowing God would be central, and the only essential one.

Good question

I believe there is a thread of truth in almost any religion.
"Faith" by definition is is belief in a system that cant be proven so not many people can be 100% positive.

However . . . . . . I do believe, I dont think there is a way I can convince you, I wont even try, that is a personal choice.
but I can give you the reasons I believe, that is probably not enough but that is all any of us can give you.

I find it impossible to climb to the top of a mountain and look out and not believe.
When I held the tiny hands of my children when they were newborn, there was no doubt of a higher power, I choose to believe, that's all any of us can do.

Not to the common lay people. Not to some of the Preachers. But there are people who know that the religion they preach is false. I expect the Pope knows very well that the premise of his religion is a lie.

Sorry to be cynical but most religions though based from the truth have been corrupted and changed some by people who know full well the lies they are teaching.

This is not all religions but some.
