THE GREAT WHITE BEAR

According to H.L. Mencken:

FUNDAMENTALISM: "a terrible, pervasive fear that somebody, somewhere, is having fun!"

This definition appears to work with virtually any religion. Just put the religion du jour in front of the word Fundamentalist i.e:
Islamic Fundamentalist
Christian Fundamentalist
Jewish Fundamentalist
Hindu Fundamentalist
See! Adding any religion immediately takes the fun out of fundamentalist. So one can only conclude:

IF YOU WANT TO HAVE FUN, AVOID FUNDAMENTALISTS!
