". . .it's like this, once you beleive your religion is the right one and the only one telling the truth, then that would make everyone (other beliefs) fake or sinners. and if you believe other relegions are correct, that would make you a sinner... so which is which?"
Your just reconstructing your question bro.
Is believing other peoples religion a sin?
By the way, let's define sin first.
From Wiki:
Sin is a term used mainly in a religious context to describe an act that violates a moral rule, or the state of having committed such a violation.
Different Religion have different views on sin. A common statement is that, its a violation of God/Allah/something/someone/ etc . . . .
Also, IMO every religion worship the same GOD unless you're the other way around.
Now, when is believing other religion (who worship the same God) becomes a sin?
