Thumb-sucking gaddamned malcontents with no moral compass and no focus in life other than to champion overblown, self-created, or 'phantom' injustices, for the sole purpose of giving their own hollow existences some sort of meaning. These were the pukes that got their books knocked out of their hands in high school; the ones who couldn't find a date to the prom; the ones who got picked last in gym class. Most of 'em never got laid until they fell into these campus collectives.
Some of 'em still haven't.
