Because the French Revolution didnt permanently damage democracy as a political system.
Ok. Neither did the communist revolutions of the 20th century permanently damage communism as a political system.
And democratic system in one form or another existed for millennia before the French Revolution.
As have anarchist and communistic systems.
The USSR and China under the CCP permanently discredited (without any chance of rehabilitation) communism as legitimate ideology.
No. They didn't. Only too western liberals who were always hostile to communism would say that. The idea that communism is permanently dead just because capitalists didn't like it is pure "end of history" Neo-liberalist nonsense, and basically ignores the fact that a large chunk of the worlds population still actively feels positively about these revolutionary projects; to say nothing of the people who don't like those particular ones, but still agree with communism in general.
Besides, so called "liberal democracies" have done far more evil than the USSR or Communist China. In fact, they're doing a repeat of the Holocaust as we speak. Does that "permanently (without any chance of rehabilitation) discredit democracy as a legitimate ideology"?
No one in their right mind would want anything to do with communism. It’s like asking for genocide, mass killings, gulags, lack of free expression and poverty. No one is going to do that.
Sure, if you're a complete dullard who has mainlined nothing but pure, concentrated cold war propaganda without any thought or consideration, without ever bothering to open a single book on political theory. Everyone else is not that stupid.
And guess what? You have genocide, mass killings, gulags, lack of free expression, and poverty now, no communism needed. In fact, communism has almost always been associated with a reduction in those things if you actually check the stats.
And I not saying this in the polemical sense used by pro-crime/pro-corruption Americans
Yes, you are. That is exactly how you are saying it.
