What gives these fringe religions like Mormonism legitimacy? All I can assume, is that Christianity, Judaism, and Islam is taken seriously because of their long history and billions of followers. Moronism is just a little over a hundred years old, with only a few million followers on one country. I can't think of any difference between the religions besides age and popularity.
