Imma copy-paste what I said in the Tranny sideshows thread, in response to someone pointing out that the tranny "born in the wrong body" claims are essentially asking you to believe in a soul, a spiritual claim that can't be proven or disproven:
"To me, from the start, it was that.
I'm an atheist, and because I'm an atheist, I have to tell you that I'm an atheist. I mention this (because I'm an atheist) because I believe in a purely material world. No souls, no spirit, nothing beyond the meat machine and its inner biological workings.
The whole thing being framed as "I'm really a man/woman/wolf/the whole cast of Final Fantasy 7 inside", to me, cannot be, because there's nothing inside.
If for some reason your iOS device starts reporting that the OS is actually Android, the solution is to correct that issue in the code. You format it, you flash the correct firmware, whatever.
You don't change the phone's shell from the one with the apple to one with a little robot, and you don't pry out the camera sensors and glue the ones from a Samsung onto the hole.
Even if we accept they're being true and honest and it's not just a fetish or some other paraphilia, if you genuinely believe it, the solution is fixing the misconception, not tampering with the body, much less in such a catastrophic way.
So by definition, if you've got a man body, you're a man, made of man-meat, every cell of your being. So whatever happens with it, your brain is a man's brain. If it appears or behaves or is construed as a woman brain, then it's the brain that's malfunctioning, and IT should be treated, not the body. Same for woman-meat, obviously.
And it's baffling to me that the atheists and skeptics and science lovers were to quick to uncritically move their goalposts the moment the trannies wrote themselves into the Oppression Olympics.
I'm an atheist, by the way."
Additionally, since it's a mental illness, a mania, I don't believe in the concept of transphobia.
I don't think we should humor people with manias, like telling an anorexic that "yeah, you're fat, keep on making yourself puke and maybe you'll get better, fatass", but no one would say that's being anaphobic (ok maybe some would, but society largely recognizes instinctively that those who would are wrong and also mentally ill).
Same for telling an addict, be it to drugs, alcohol, gambling, or whatever, that it's fine to indulge, just one more hit has never hurt anyone. NO ONE thinks humoring them is acceptable, or that opposing those behaviors is hate speech or a hate crime.
So why the fuck call people transphobic and bigots for having the opinion that mentally ill people shouldn't medicate and mutilate themselves to match a completely subjective misconception about their body image? Fix the misconception, you retards!
