Do trans people think their genitals are evil? No.
Do people exist who want their limbs cut off? Likely very few.
Do people exist who want bottom surgery? Yes, plenty and they are transgender and we have concluded that nothing is wrong with these individuals.
You fools want to act like changing your gender is the same as changing your species or getting gender affirming care is the same as affirming yourself as having no legs. These people just want to be their authentic selves and have simple respect and acceptance from the people in their lives. Why is that so f**king hard for you?
