I agree, it looks pretty bleak. There's no question that PC is cultural Marxism, and that it's been inculcated in our schools and media by design.
What will forever puzzle me is how we as a society have become so weak and stupid, that we can no longer see the likes of Hillary and her ilk (interestingly, "Blacklisted" is the first time I've seen the name Alan Cranston in print for a while) for what they are. In conversations with people, particularly young people, I often feel like I'm talking to somebody who's been hypnotized.
I wrote a long, long response to your comment but abandoned it because it just became too burdensome. Boiled down it amounts to three things: domination of the popular culture -- everything from Che Guevara T-shirts, popular music and late-night comedy shows -- all with a relentlessly liberal point of view; and,
Domination of the education system, using a preferential hiring system to make certain only one point of view is available to indoctrinate students, and;
Domination of the mainstream news media to twist and fashion the day's news into a liberal-progressive-socialist single-message propaganda campaign.
It was frightening to me last week to hear how CNN flying monkeys framed the Democrat recess appointment strategy. They were keeping Congress in session, we were told, to circumvent the sneaky, evil Republican Bush from pulling a "fast one" on the American people. The fact that the President's recess appointment power is in the Constitution was either unknown to the snotty little blond talking head, or of no consequence.
This is getting long again but I forgot to mention one thing: none of this would have been possible without the total dumbing-down of American education. It was brought about by the rise of the know-nothing "education" departments in university teacher curricula; unions that only care about teacher pay increases, reduced workloads, more perks and longer vacations; and certain "parents" that never grew up themselves.
