Cause-worshiping
nut cases in colleges who become activists. They protest whatever they can because they need a cause. Feeling superior to everyone else because they're "fighting for something" is why they wake up in the morning.
SJWs are a prime example of this. They feel they are fighting
racism to the point that they turn into racists themselves.
They fight for leftist conspiracy theories such as
autism-causes-vaccines nonsense, or against GMO, against nuclear energy, against "social injustice", against "
racism", against Wall-Street, or against animal testing...
Or they fight for right-wing conspiracy theories such as neo-nazism, fighting against the "establishment", against the
illuminati or against FEMA, against even legal immigrants, or against the government because of that one tax bill that pissed them off.
