is it fair to call someone else's religion wrong?

I don't know if it is reasonable to call it wrong. But there are some religions which are illogical and teach people to do some bad things.

So long as people are not getting abused, EX. the polygmist children that were taking away. Then i think its fine, people have a right to freedom of choice, and that includes religion. Whatever makes ppl happy is good enough! YOu do what makes you happy and ill do what makes me happy lol.

There is no wrong religion. No religion is the one true way, despite what many religions are trying to spout to people. It's called brainwashing. The fact is, we don't know if there is any one true religion, we don't know if religion is even a viable resource that humans have or need. The truth is, we won't know until it's the end.

There is no such thing as a wrong religion! To each their own.

I don't believe in a "Wrong" religion. Everyone has their own beliefs to keep themselves at a piece of mind.

Not wrong but intolerant yes like some folks believe is ok to discriminate against something they do not understand or fear.
