Only some of those in that alphabet soup are actually gay. It's a dishonest catchall especially adding those born Intersex on the end as some do. Also there are various kinds of T.
Indeed whatever the studies are showing, is it actually gayness or based on structure? Is there even one universal definition of "gay"? Is the accuracy claimed based on self identification on the photo posting only? What is the definition used by photo poster and are they honest?
I'm sceptical as to how reliable the sources are and the results are. Also what age ranges?
