When the topic of communism comes up in the US, most automatically dismiss it due to the tens or hundreds of millions who died at the hands of communist regimes.
As a counterpoint, some say that the amount of mass murder caused by capitalism is comparable. Thus, if mass deaths are used to dismiss communism, then capitalism also should be discredited.
Is the counterpoint premise valid, that capitalism has caused an equivalent amount of mass death as communism?
UPDATE: Since I cannot answer my own question, here is the relevant wiki article. The question has been investigated and communist regimes apparently have killed many more people than any other sort of regime.
Daniel Goldhagen argues that 20th century Communist regimes "have killed more people than any other regime type." Other scholars in the fields of Communist studies and genocide studies, such as Steven Rosefielde, Benjamin Valentino, and R.J. Rummel, have come to similar conclusions. Rosefielde states that it is possible the "Red Holocaust" killed more non-combatants than "Ha Shoah" and "Japan's Asian holocaust" combined, and "was at least as heinous, given the singularity of Hitler's genocide." Rosefielde also notes that "while it is fashionable to mitigate the Red Holocaust by observing that capitalism killed millions of colonials in the twentieth century, primarily through man-made famines, no inventory of such felonious negligent homicides comes close to the Red Holocaust total."
