Murder and rape are wrong even if they do occur in nature. It is this notion of equality that Karl Marx incorporated into his socialist theories, and it is this premise that makes raping and killing wrong even to evolutionists. Unfortunately for Mr. Perks's case, communism's rejection of organized religion cannot be seen as the culprit. Fundamentally, socialism is about the equal treatment of individuals, and the rejection of social classes. In fact, one might argue quite convincingly that Jesus himself was a socialist.
Multicultural tolerance is also the underlying attitude that makes Canada so wonderfully diverse.
Although rape and murder are problems faced by all countries, Canadians do not suffer disproportionately from them as a result of our multicultural heritage. Thus, there are two ways of preventing ethnic cleansing. One, accept people's differences or two, make everyone the same. This latter view, which is clearly espoused by Mr. Perks, has the unfortunate consequence of leading to things like the Crusades, the Inquisition, and the Holocaust. The theory of evolution is not to blame for the atrocities occurring around the world.
