I knew my cousin was gay long before either of us hit puberty. So did he. I also knew that I was interested in both boys and girls long before my concept of what I might like eventually like to do with them coalesced into more concrete terms. The emotional stuff is there before the interest in sex is.
I'm not surprised that most people in any group find what's happening with Desmond and Nevis disturbing, so not surprised that most people into drag do. What's interesting is the failure of the people who don't see the problem to notice how out of step with most other people's perspectives they are.
Say to just about anyone "so there was this 11 year old dancing on a stage at a club full of adults, many of whom were drinking and/or consuming other recreational chemicals, and the adults were throwing money at the child" and their response will be "WTF, is that even legal, are the parents out of their god damned minds?"
