Religion is a choice, at some point in your life there has been an active decision to start or continue believing something. Snake Midget is a great example, he was raised a muslim and then chose to stop believing in it. Mocking people for believes is not disgraceful, if you have chosen to believe it then you it is entirely YOUR fault for doing it. Mocking someone for the colour of their skin, hair, eyes is something that they cannot choose and therefor is morally corrupt.
Don't tell me religion isnt a choice but it just is. End of.
