It's not a mistake of natural..... That's very insulting and disrespectful beyond belief. They ARE a third sex. "When possible avoid expressions like mal-developed or undeveloped, errors of development, defective genitals, abnormal, or mistakes of nature. Emphasize that all of these conditions are biologically understandable while they are statistically uncommon" - milton diamond, one of the most experienced professors of human anatomy and reproductive biology. Intersex people are a third sex, not a mistake of nature. A sex is not the same thing as gender. A sex in a term used for describing the biological sex organs a person has, a gender is identity like androgynous, agender and binarism. There is a difference between the word "sex" and "gender".
In theory a species could have hundreds of genders although that would be incredibly inefficient .
I base gender of the production of sex cells humans only produce eggs and sperm so only two genders/sexes.
If someone produces both they are both male and female but not a new gender .
Lol no because in this case the definition doesn't make logical sense and shouldn't be applied to the the real world. Go ask a stranger on the street what defines gender. They will say 100% of the time it's your reproductive organs.
You know I'm right. Your DNA, penis, balls, etc. make you male while your DNA, vagina, breasts, etc. make you female. Regardless of what a book says this is fact. You're an Atheist like me you shouldn't follow a book blindly.
