Communism Parade

I was biking home past University Ave. in Berkeley, California, and there was a large parade blocking traffic. In the parade were three people holding up a very large red banner. It said we need "revolution and communism" and something about not wanting more "empire". One of the people in that group had a loudspeaker. He said when people call communism a horrible failure and an atrocity you're stripping away and ignoring the history of the masses of people. The next group had people dressed as Klingons.
