Some say the Left ruins everything. When I think of what it has done to the Boy Scouts, to sports, to the military, to churches, I'm inclined to agree. But what do we expect? Increasingly those on the Left are opening up with their Marxist, pseudo-communist leanings. They fully reject God and the Gospel and Jesus Christ. They declare their opposition to the Bible and the Christian values and teachings of the Faith. They make plain their desire to throw down the Christian West and the American experiment. Therefore, those who see value in the heritage of Western Christian civilization can't help but see the destruction and damage done to all areas of life this movement touches, including art and our basic values and cherished principles.
The above clip looks to be in response to calls for the removal of Gone With the Wind that happened a couple years ago. His dig about the hallowing and sanctifying of Presentism as the Left's prime approach to history was nice to see. An approach universally condemned in my undergrad and graduate days, it has become the exclusive approach to studying the Western tradition over the last two decades. I'll leave you to figure if this approach has helped or hindered the quality of our cultural output.
