Gender should be assigned by genitalia and chromosomes at birth.
Correct. Genitalia actually does not always indicate the sex (use of the word gender is incorrect) of a person. It is the xxx and xy chromosomes that tell the truth, and no surgeon’s knife can change that.
“Gender should be assigned by genitalia and chromosomes at birth.”
Sex is assigned at birth. Your birth certificate says you are either a male or female.
When you turn 16 you can assign your own gender. You get a nice drivers license with all your gender specific information. However, on the card it still says “Sex (XX/XY)” It is actually a fair compromise. Your gender can be female, but your sex is still male.
Historically, gender has always been a physical designation. It's the Democrats who redefined it a as psychological trait.
