Nobody is mutilating-they are removing what isn't needed--I had 2 perfectly healthy back teeth removed, too many teeth, they were not needed, too hard to clean--the dentist took them out--no mutilation. They are correcting a problem they had no choice in making in the first place!! And it is your contention that it is a mental disorder, when it is a physical deformity, whether the parts are healthy or not is not the question--they are the wrong parts!!!
"removing what isn't needed"
well God gave them a healthy body
if they want to be poor stewards of His creation and mutilate a healthy body, that sin is on them
as for removing some teeth because they were hard to clean
there is a utility in that
a reason
it is not from a misguided view of reality
if you do not clean the back teeth properly, they can get cavities and cause a lot of pain, so it makes sense to get them removed
so called "sex change procedures" do not follow logical thought
it is does not turn men into women
run a DNA test if you do not believe me
it makes feminized men
Romans 1:24-27
24Wherefore God gave them up to the desires of their heart, unto uncleanness, to dishonour their own bodies among themselves. 25Who changed the truth of God into a lie; and worshipped and served the creature rather than the Creator, who is blessed for ever. Amen.
26For this cause God delivered them up to shameful affections. For their women have changed the natural use into that use which is against nature. 27And, in like manner, the men also, leaving the natural use of the women, have burned in their lusts one towards another, men with men working that which is filthy, and receiving in themselves the recompense which was due to their error.
