3 neopagan religous movements

As you remember from school: there are three the biggest religions in the world: Christianity, Islam and Hinduism. But there are also some natural religion we call “paganism” (but “paganism” is a word which describe only non-Christian religion, in Meddle-Age that word was offensive; today we understand “paganism” as primitive, natural religion without any system). There is also Pagan Federation International, which popularize Neopaganis.
