If you're talking about conservative/progressive status quo people, don't worry about them they are doing absolutely nothing. They are the kind who will be freaked out if the regime is overthrown but they won't do anything about it and remain passive little gears of whatever system they are thrown in.

If you're talking about how all western left leaning people are deeply liberal, with the "libertarian Marxists" the anarchists, the succdems and other kind of moralistic leftists then I understand your concern. But you must also consider that those terminally white ideologies are a result of the imperialist-enabled mode of production in the west (ie. Having everyone doing service jobs while all industry is abroad). Since imperialism is in the process of collapsing, this model will eventually decline and ideology will follow.
