[You're a mean one, Mr. Day, you really are a Beale]
The reason the ideological Right has limited cultural power these days is because the Left, with (((David Brooks))) and his nation in the vanguard, have worked very hard for at least four generations at attempting to eradicate everything from the culture that betrays any sign of Christian influence or Western tradition.
And the reason that they are failing despite their near-complete control of the cultural high ground is because they have literally nothing to offer in its place. All they ever had to offer was reaction, negation, ugliness, filth, and snark. Sure, you can adulterate Christmas, and you can substitute Silver Bells, shopping, Santa, and Seasons Greetings for Silent Night, Hark the Herald Angels Sing, Scrooge, and We Wish You a Merry Christmas, but at the end of the day, either you come up with a substitute or your efforts will eventually prove futile.
What did they come up with in over a century of frantic effort? Festivus, the Hannukah Aardvark, and horrible movies that are bad even by Seth Rogen's standards. Hardly an attractive exchange for even the most godless pagan.
We not only can win this cultural war, we cannot lose it so long as we continue to create things that are good, beautiful, and true, and continue to refuse entrance to the infiltrating wormtongues who are always there with their helpful blandishments and seductive offers to sell your creative soul to Mammon.
So let them turn Elsa of the Crowleyesque anthem into a lesbian. Let them transform Superman into an SJW superhero fighting for global migration, one-world government, and AIPAC. Let them continue to preen and posture and sneer and snark in futility. It will avail them nothing. Like their Father the Devil, they cannot create, they can only corrupt. And that is why the greatness of Tolkien, of Howard, of Lovecraft, and of Wright will continue to be recognized over time despite the Left's best efforts to denigrate and diminish it.
