There's a reason why liberals admire the likes of Castro and call communism in Russia a pivotal experiment.
When most of us look at how countries crumbled under communism, we see why it's an unsustainable, oppressive and horrible way of life. When liberals look at how countries self-destructed under communism, they see leaders living their dream and they think they can do better than the last dictator.
The people who are willing to go in that direction are either leaders with delusions of grandeur or people who think being taken care of, like a child, sounds good to them. The leaders always sound benevolent at first in order to coax people to go along with the idea. By the time people realized they were duped, it's too late.
Right now, a lot of people are successfully being duped and the number is dangerously close to those who still see the truth. Once we are outnumbered by them, it's all over.
Voting new people in office is helpful, but educating people on history is needed more than ever.
