For a man who claims to read so much, you obviously didn't read what I said in my post,  only what you wanted to believe what I was saying. I said absolutely nothing about "sexual preference".  XXY, XYY and other permutations are very common in people who experience gender dysphoria, a common condition of the transgender. I'm sure you will argue that dysphoria is a myth or fabrication. Feel free to argue it with those who have been driven to suicide by this fabricated condition, successfully or otherwise. Ignorance is often exlpressed as arrogance.  Have a nice evening.
