I think that it has all those trappings, but underneath is a deep addiction to anger, outrage and the rush of adrenaline that accompanies it.
There is also a sort of religiosity that your comment alludes to.
>Various thinkers have pointed out that leftism is a kind of religion. Leftism is not a religion in the strict sense because leftist doctrine does not postulate the existence of any supernatural being. But, for the leftist, leftism plays a psychological role much like that which religion plays for some people. The leftist NEEDS to believe in leftism; it plays a vital role in his psychological economy. His beliefs are not easily modified by logic or facts. He has a deep conviction that leftism is morally Right with a capital R, and that he has not only a right but a duty to impose leftist morality on everyone.
