It's not any different than any other psychiatric dysphoria, and I reject politicized redefinition of words like gender.
If an adult who think's he is a parrot wants to cut his ears off or someone wants to remove their genitals whatever makes them happy but I draw the line at being compelled legally/civilly to acknowledge someone is a biological parrot.
What I find interesting about the latest DSM reclassification of gender dysphoria is that it was reclassified for political purposes with objections from the actual psychiatrists that were in charge of the entire transsexual criteria. The left basically used their political power to further divide the rest of us using the trans people as pawns. I'm going to stick with the prior DSM classification as that's what the psychiatrists who authored the section say is the best thing to do. It's funny that the psychiatrists who objected to the change were labeled as transphobic when they were simply objecting to the politicization of the topic.
