The long history of "Western Civilization" includes the divine right of kings, continental-scale genocide, colonialism, and religious subordination to the Pope (or at least to Christ). Yet the author - a self-proclaimed "right-wing curmudgeon" - seems to reject those historical tenets of Western Civilization, when supporting how "The past 50 years have been marked by the genuine eradication of barriers to opportunity for the underprivileged regardless of ethnicity, sex, sexual orientation or anything else." I somehow think the author doesn't mean to include fascism, communism, and Marxism as part of the "Western Civilization", but instead uses that term to mean the parts he likes. Which his counterpart 100 years ago would have declared to be the death of Western Civilization.
