Liberals need to erase history in order to demonize Christianity and "the patriarchy". If you told people that Christianity and white male patriarchy built roads, established democracies, a court system, human rights, built trade routes, bridges, planes, hospitals, defeated nazism and even sent a man on the moon, women and immigrants would be incredibly thankful to white men. Obviously the truth is intolerable to special interest groups, which capitalize on being "victims". So history needs to be concealed and rewritten, in order to allow for the type of outrage-culture we have in today's universities. Demagogues you say? yeah, Justin is no better than your average journalist and mainstream media outlet. No shortage of demagogues here either.
