Krisi's point (a question, actually) is being missed. It's not comparing crossdressing to criminal behavior, but asking if it's possibly the same mechanism that determines different "attributes", without speculating on what that mechanism might be. We are told if you're a crossdresser, accept it because you can't change it. I have wondered this about habitual criminals. Let's take serial killers, for example. With no personal connection, no revenge, nothing financial to gain, some people seem to have an insatiable need to kill strangers. Some have confessed that "if you let me out of prison, I'll do it again. I can't help it. I don't know why". Could some genetic "copying error" be the cause? What causes one to crossdress? Or kill strangers? If we want answers to these and other unknowns, we must allow questions to be asked.
