It is my personal belief that no religion is wrong. Its how you are a follower of it. Almost every religion wants you to be a good person and love all, but that is rarely done. (myself included) I look at it this way, if you are a good person, you live your life good, spread whatever religion you have in a constructive way without harming anybody, and you don't condemn any one kind of people or religion, then you are really doing the essence of faith.
And, even if we who believe in a religion are wrong, then we have still lived good lives and made the world a better place.
