I will not respond to everything because that would require a whole book but please let me highlight some historical facts that I feel you might have confused. You imply that famines were a regular occurrence under communism, this is wrong.
The was never a single famine in the Soviet Union after World War 2. In fact the CIA concluded that the Soviet citizens ate a similar amount of calories with slightly more nutritious food. [0]
Furthermore the idea of famines being typical for communism is contradicted by the basic historical fact that famines were a regular occurrence BEFORE the Soviets took power. The communist regime stopped famines from happening.
Comparing a famine that happened after the country was ravaged by the first world war AND a horrible civil war AND huge societal changes to planned industrial murder is insane.
> Nations plunged into poverty for generations.
Considering that Czarist Russia happened in one of the most backwards places on earth where people still used the wooden plow I would say the Soviet Union becoming a serious competitor to the US is very impressive. And current day Russia is doing rather well all things considered, surviving against at Western sanctions much longer than many predicted. I wouldn't want to live there but it is certainly doing better than many other countries in this world. China has seen a meteoric rise to power under a "communist" leadership. Cuba provide a vastly higher standard of living than comparable countries like Haiti.
It was mostly impoverished countries that have seen communist revolutions. You are confusing cause and effect.
Yes, Western Germany has done very well but is mostly due to the huge investment of the US in it as it was needed as a bulwark against communism.
We have an example on what the communists would do with Germany in Eastern Germany and well it is not very spectacular. No famines. No mass murder. The main issue where of course the wall between Eastern and Western Germany which separated families.
I will not deny the atrocities done during the Chinese Cultural Revolution, they are stomach turning. To say they are typical for communism is a bit dishonest considering the Soviets denounced Mao to the point that diplomatic ties broke. If we played the game like that, we would have to say that the Irish famine or rather genocide is to be considered typical for capitalism.
I don't really like comparing atrocities. Every single one is bad enough on their own.
The main point is that anyone with a shed of humanity has a duty to be anti-fascist first, after that we can battle out whatever system is better or worse.
