So it's not "insane". Very well; why is it "sane"? Why is it sanity to claim to be something you physically are not, except you "feel" that is what you should be? So we define ourselves based on our feelings? When was it that we began basing logical decisions on our feelings rather than on factual evidence?
Let's look at it another way. I would be considered certifiably insane if I believed I was Abraham Lincoln. Yet, by the so-called logic of the LGBT movement, if I have surgery to make me look like Abraham Lincoln, and if I dress like him and talk like him, I should be considered to be him! Because, if you tell me "you're not Abraham Lincoln, bro", you're interfering with my self-identification. I should be allowed to choose how I identify, based on what I believe I should be.
Obviously that's insanity; I'm not Abraham Lincoln. You might say "that doesn't count because you can't become someone else who already exists." Exactly my point! Just because I might want to be Abraham Lincoln, and might try to look like him, hell, might even have surgery to make me physically identical with Abraham Lincoln...I'll still remain the man I was born as, at the end of the day. Except I'd be disfigured by my own illusions.
Except it's now possible to have a sex-change. So my argument is invalid...isn't it? Not remotely. I was born caucasian. However suppose I believed I was really African-American, and I was born white as a mistake? Suppose the medical technology existed which could turn my skin negroid? Would undergoing that procedure change who I am? Would I become African-American just because outwardly I looked like one? Because I "believed" I was one?
Or suppose I had a horse tail grafted onto my backside. Would that make me a horse? The term for what that would make me, I believe, is a lunatic horse's ass...
No. If I tell people I'm Abraham Lincoln, they'll tell me I'm crazy. If I tell someone I'm black, they'll look at me funny and tell me that I'm very much caucasian. If I tell someone I'm a horse's ass...umm...actually, they'll probably agree with me on that one...
Someone who has a heart transplant - does that make them another person? Nope! The heart changed, but the person didn't. If they have a limb transplanted, do they become a different person just because their limb is different? Again, no. They are still the same person, even though a PART of them has been replaced with something different.
