So has anyone died as a result of the communist manifesto? Was the media to blame for the deaths during the riots when they lied about US soldiers using the Koran as toilet paper?
Was Christianity at fault for the burning of supposed witches?
I say no. Just like I say no to the other things. Flawed human beings, in their quest for power and control, subvert and pervert theories and belief systems to their advantage. There is nothing in Marx’s writings that supports the gulag, nor is there anything in Darwin’s writings that support the ethnic cleansing (read: wanton murder) of Jews. Flawed humans, again, in their quest for power and control instituted those things on their own.
I believe that the events of the 20th century that you attribute to the biological theory of Charles Darwin would have happened regardless.
