Turns out having a modicum of respect and understanding for working class people is what they're after.

Yeah, my communist org is big on this. The first thing we do when we talk to members of the public is ask them what issues matter to them. Everyone is being hurt by capitalism even if they can't name the problem, so simply letting people talk about their experiences and concerns lets us build a connection and discuss how we're fighting for those causes. Being unaffiliated with the Democrats is probably a huge boon there, since we don't carry their well-earned baggage of being considered condescending and out of touch.

Obviously, a small business tyrant CHUD is a complete nonstarter, but we can almost always find something to fruitfully discuss with even right-leaning lumpens.
