Whoever wrote this garbage needs to read up on history. Who wrote this? A failed first-year arts student? Or some weed-smoking clown who reads too much Chomsky? My history ain't that great, but just for comedy:
To have Stalin there is telling alone of this person's seemingly limitedless stupidity. Stalin is a man both directly and indirectly responsible for killing over 20 million of his own people just to bring potato-farming Russia into the industrial age - meanwhile we're complaining about the 7-day work week of Victorian Britain. Incidentally, do we know what Feudalism was? Guess how many hours farmers and labourers worked back before capitalism came to town? The idea of a vacation, which I’m sure everyone here is familiar with, didn't exist a couple of hundred years ago.
The points pertaining to WW2 are mostly a result of Nazism (ie a form of socialism albeit a very evil and racist one) and the combat against this evil.
Hiroshima was the tactical response to an indoctrinated group of people who quite literally thought their ruler was descended from a sun god. It was either that, or a war of attrition.
Racism? Right... And no socialist (bar the Nazis of course) has ever been racist?
The great bulk of these wars and battles (Boer, Nanking, Opium) were a result of imperialism and colonialism, which are not mutually exclusive to socialism. The Russian Empire didn't let go of their annexed states once they became the Sovient Union. Also, China is still fiercely holding onto Tibet (as most whining hippies will know).
McCarthyism was an extreme response to an exaggerated fear by a madman (who, incidentally, didn't slaughter his perceived enemies like our socialist amigos Pol Pot, Mussolini and Stalin).
Exxon Valdez? Both capitalist and socialist countries trade in oil. Just ask the socialist clown Hugo Chavez.
The Mafia? Organised crime? So China doesn't have organised crime? Triads are just a myth? And Italy was never a socialist state?
Tuberculosis? Electric-chair? Pure insanity. What's next? AIDs? Cancer? The common cold? Or are they products of lizard-like aliens?
This is just off the top of my head. If I could be bothered doing some research, I would find even more gapping factual and logical holes in this poorly construed "argument". This sort of mentality is frightening, to say the least.
