Speaking of the trans mentally ill, if there are any lurking DUmmies here, I want you think about something in regards to “identifying” as something that you are not.
Let’s say that somehow, someway you have a friend who is on top of the Empire State Building with you, and this friend tells you that he identifies as an airplane and is going to jump off of the building and fly to Chicago real quick. Would you encourage that delusion, tell him to grab you a t-shirt while he's there, and let your friend jump to his death? You have to know that, no matter how much he believes it or how much he wants it, he can’t fly and just has a mental illness. If you say that you wouldn’t let your friend jump to his death, why would you encourage the delusion of someone who “identifies” as another gender?
