ESPN article on W swimmer G Ryan who is genderqueer / non-binary

The American Psychiatric Association, publisher of the DSM-5, states that "gender nonconformity is not in itself a mental disorder. The critical element of gender dysphoria is the presence of clinically significant distress associated with the condition."

Your statement seems to lump all of those experiencing gender noncomformity as being afflicted with gender dysphoria, and so in need of mental help for their mental disorder. That may not necessarily be the case. That may be why some appear to be reacting strongly to some of these comments. No one wants their friends or relatives to be called mentally ill, or mentally disordered when they are not.

As others have pointed out in this thread, there are situations where people have something other than XX or XY chromosomes*. The folks on here saying have XX and XY divisions and claiming scientific superiority come off looking like the believers in Newtonian Mechanics after the discovery of Quantum Mechanics. Things aren't always so simple as they appear.

I have a relative who transitioned last year. I was very surprised to find out how much I didn't know about the issue. The statistics regarding attempted suicides among this community are horrific. It's also sad that the significant distress associated with gender dysphoria is often a result of ignorance of the issue. In other words, the distress is caused by society's gender norms and inability to accept individual's choices that are different. I don't care if a young boy decides they prefer to wear pink, have long hair or play with Barbies. They shouldn't care either. But when society tells them they are wrong for doing these things, it shouldn't be a surprise that they feel significant distress.

Imagine you're inherently unhappy with something that takes massive effort to change...Like your body and what it's trying to be. Imagine you find the courage to tell your parents...and they don't understand, or get mad, or reject you. Imagine that you manage to take steps to correct the things you feel you need to correct...and everyone judges you for it. And imagine that there are political debates and internet forums which center on how human you are, whether your happiness is something we should accommodate as a society, and whether you should have basic American human rights. I don't think I'm strong enough to make it through all that.
