By Dennis Prager, Townhall - But there is something people deny more than mortality: evil. Someone should write a book on the denial of evil; that would be much more important because while we cannot prevent death, we can prevent evil... The most glaring example of the denial of evil is communism, an ideology that, within a period of only 60 years, created modern totalitarianism and deprived of human rights, tortured, starved and killed more people than any other ideology in history.
