AM CONFUSED! Male, female, trans... why does "Cisgender" exist in this? isn't same as... "man - male" n "woman - female?"

If one has a penis,male.
If one has a vagina,female.

It's a way for a relatively small group of people who have been labelled and discriminated by the mainstream to label and discriminate back.

I refuse to get drawn into that pile of crap. There are two biological genders, male and female and if you can't tell the difference then you have a problem.

It is. I don't like being called "Cis". I have two X chromosomes, a uterus, breasts, and a vagina. I am a woman, I am female. That is all.

Cisgender is a person who feels comfortable only in the field in which he was born. That is, a woman born to a woman feels normally only as a woman
I myself do not understand why this ...
