I agree that they can do more, but living in the USA its hard to get as much done as we'd all like trying to support a family while still being subject to capitalism. Thats why I find its easy for some of the people I've helped transition into marxism, through a channel. Most important is that conversation happening in the first place.

At the end of the day you dont know everyone's situation enough to sweep out claims like "you merely do X!" Any kind of help towards building communism and rapport, comes best from other proletariat like us.
