Petty bourgeois "revolutionaries" that would rather sit in an office than stand on a picket line, call out culture, 'safe space' policies, 'check your privilege', identity politics, spending more time arguing on the Internet than doing much of anything meaningful to improve the lot of the people, the fact that the left seems unwilling (or unable) to engage in meaningful organization outside of major metropolitan areas, lifestylism, sectarianism, unwillingness of radicals to go out and organize unions (which is literally what the left is going to have to do if it ever wants to be relevant again), and a general lack of community among left-wingers.

Bad news tnf, Cory just agreed with you
