When I was young, I was a follower of Classwar, the only revolutionary group that made any sense, and weren't interested in cultural Marxism. I was also a member of the IWW, a world wide Syndicalist workers union. They're both explained on Wikipedia if you're interested.
The thing that these two groups were - and are still - very good at is agitprop. They knew just how to get the message across -the Classwar newspaper beat Socialist Worker hands down too.
Of course, anarchism, socialism, capitalism - all bollocks, but, when you're young, everything seems possinle.
