> If you the idea is crap and it proved that it's crap by leading to genocide why would we award it any protection?

Lots of communists say that the Soviet Union wasn't "real communism". Yet I never hear the same outcry against that.

I am not saying it should be "protected". I am saying that individual liberties should be protected and one of the most important (after private property rights) is the freedom to speak you mind.

> Do tou think next time around, it will lead to something beneficial to mankind?

No.

> It did not lead to genocide. The first time it does I hope it's banned to hell.

When people questioned the idea that the Earth was the centre of the universe people were punished for such ideas. So that has kind of already happened.
