According to a disturbingly pleasant graphic from Information is Beautiful entitled simply
20th Century Death, communism was the leading ideological cause of death between 1900 and 2000. The 94 million that perished in China, the Soviet Union, North Korea, Afghanistan, and Eastern Europe easily (and tragically) trump the 28 million that died under fascist regimes during the same period.
Infographics brought to you by your friendly capitalist. Please look the other way while we plunder yet another country not so near you, killing its population in the name of increasing our capital under the fig-leaf cover of "bringing democracy".
When the more virulent form of oligarchic capitalism was brought into Russia, resulting in the "Wild 90s", it resulted in millions of deaths only in that decade alone.
I always sort through tumblr's many porn pages to get the truth, seeking historical facts first, before any other places. Not from books made out of paper. Not from actual witnesses.
I am guessing the message I get from your link is:
"If capitalism did it, why be sad about communism killing people? Same thing..." What you are doing here is a classical form of Ad Hominem attack on the source, rather than addressing the material quoted. Beware, here be logical dragons.
