The "non-sexual" attitude here is, I think, a bigger problem that needs more discussion (and I dont' remember if I mentioned it here or IRL). The problem, I believe, is that these people aren't lying or are disingenuous when they claim that Desmond's act is "non-sexual": it's just that they have moved the Overton window just too much to the left. If you make drag queens "normal", if you remove the definition of sexual identity, if you say "virginity is a social construct", "kids are queer", and you insist that sexual intimacy is repressive, then a kid dancing for strangers is not remotely sexual either, it's just him or her expressing themselves.
Or, better said, for hardcore degenerates, a kid dancing among prostitutes is not a big deal.
