The Evangelizing Meme

Imagine two groups of people. One group's way of life is directed by a set of beliefs that are very relaxed... very live and let live. The other group is directed by a set of jealous beliefs so that these people insist that other people believe and behave in the same way. Obviously the more aggressive evangelizing meme will thrive. There is no connection to truth here anymore than dandelions are more true than grass. The meme for aggressively converting as many other minds as possible must have been selected early in the development of cultural evolution.
