As far as this goes, I sympathize, but I find it's far more easy to convince people of the benefits of something by saying, "Hey man, how would you like a government that did this? Or how would you like your workplace to be like that? Well, that's socialism/Marxism/etc." And then because you snuck it on them, they're forced to actually think about it instead of just write it off and say, "Oh well Communism doesn't work, it's a failed system it's a blah blah blah."
