Proselytising

What is proselytisation? Is it the person who has a religious bent trying to persuade people to change their belief to follow his? What about the person who joins a group that is satisfied with their beliefs and then tries to enlighten them? Is that kind of person proselytising? Yes they are! The enlightened are just as strong on proselytising as the fundamentalist, except the enlightened despise the fundamentalist as ignorant.
