You know, I didn't even know the Smithsonian had a major artistic display by homosexual artists. Until the right-wing activated their "Christ in Pee" narrative - you remember that one, dontcha? It exists because of that one time some no-name artist somewhere recieved a small government grant for crappy art that no one would have ever heard of or seen if it hadn't become political.
Anyway, activation of this narrative scared the pants off a Simthsonian curator while he was traveling, and had a piece of negligibly controversial art removed from the exhibit. A small skirmish in the culture wars, to be sure, but the censorship vs. liberals-hate-Jesus conversation always starts up when Congressmen have to start making actual budgetary decisions, and need something else in the papers and editorial pages.
It is like the Breitbart video-splicing racisim-into-a-speech-against-racism firing of Shirley Sherrod. People are now more frightened of right-wing fever dreams and fake controversies than ever. The GOP Gangsta Rap strategy continues unabated.
