I'd say communism is an example of a political theory that needs to be discussed, and in theory doesn't sound too bad, but in application, stinks. LOL
And has proven, ultimately, to be impractical and not very workable. But, we North Americanos sure spent a lot of time and energy being so scared of it that we did some pretty nasty things to ourselves and our own citizens because of that fear.
All over something that really isn't very feasible as a reality. Sometimes, the wait and see approach is better than the "flinch before you're hit" approach, and this is a good example.
One thing that happens when people latch on to a big sweeping unprovable belief that sounds just dandy but doesn't have a lot of thought or substance behind it is that they tend to clutch it like a baby monkey to a terry cloth "mother" when it offers nothing that will truly help them.
We all know that's how cults and political extremists get their toehold. It all sounds so unbelievable that a man who looks like a bad Elvis imitator, Jim Jones can convince thousands of people he's Jesus, or that Islamic terrorists can convince young teenagers to run into an embassy with a bomb strapped to them and detonate it so all the world will become subject to Islam, but they can.
It's frightenly easy when critical thinking is suppressed, even if the thought that comes out of it is unfeasible or inapplicable, at least the critical thinking function is encouraged.
Ironic that some people believe that the way to counter cults or extremist political ideologies is REPRESSION or restriction of thought, when the opposite is true in practice.
We tried that in the 50s with Communism, repress, repress, and did it stop communism? Actually, to some rebellious types, it made communism seem more exciting and forbidden. (You'll always get the "I must have the forbidden fruit!" bunch.)
No, but when critical thinking dissected the system publicly and critically thinking writers related what it was like to live under and history itself proved it eventually unfeasible, that worked much much better.
The only people afraid of commies now are people who can't actually define it two gud.
