You're still refusing to acknowledge that gender and sex are different.No, they are words for a person of the male sex, and a person of the female sex, respectively.
You want to persuade yourself that one can change into the other.
They can't.
That;'s you, right there, denying the existence of transgender people.You are implying that a person can only have the gender that complies with the sex label with which they were born.
A man can be a woman, if he so desires. If you refuse to accept reality, that's you denying the existence of transgender people. It's called transphobia. it's active TERF, when you post pictures of criminals, that's fomenting hatred towards transgenders.
No-one can change sex, but gender reassignment treatment can enable a man to resemble a woman. No, it can't enable a man to become pregnant, yet, but being a woman is not simply about reproductive ability. As far as transgenders are concened, becoming pregnant is not a priority. They can be as close as they can get to resembling a woman as current medicine and science allows. If they really want to have children, they can do what other infertile women do: surrogacy or adoption.
BTW, sex is not binary, nor immutable, it's a label assigned to a baby at birth, based on a visual inspection of their genitals.
