No religions are right. Religions set up a false system of ideas that, among other things, can either comfort a person with pleasant fantasies, or push them in to the way of the leader. Sometimes they can be advantageous in helping someone grieving the loss of someone close or other moments of need, but far more often they are disadvantageous when religious oligarchies deny basic human rights and cause psychological trauma when threats are made as to what will occur if they do not follow.
I have certain criterion that a religion must fulfil if I am to consider it harmless. Unfortunately, the majority of religions and religious groups are the bane of society.
Edit: FSM is the one true religion. His noodly arms comfort me, and destroy his enemies.
Edit 2: One of my favourite quotes is “You can safely assume you have created your god in your own image when he hates all the same people you do.”
