CMV: Gender shouldn't be as debated as it is.

It seems gender debates has entered the forefront of worldwide discussion. My argument is that gender is not a complicated topic and all this debate is unnecessary.

I suspect the top debaters of the topic understand this but purposely keep it confusing for social media following and virtue signalling.

Sex is what genitalia and accompanying hormone balance you have. There are three sexes male, female and intersex. 

Males genitals include the; penis; scrotum; and testes to name a few. Females genitals include the; ovaries; labia; clitoris; and vaginal opening. Intersex is when it cannot be classified in either. 

In order to change your sex (aka becoming a transexual human) you must change your genitals and accompanying hormone balance. 

Gender has no rules, you can call yourself any gender  and change your gender (aka becoming a transgender human) at a moments notice, no genital or hormone change is required to become a transgender human.

Male and Female sex are often used as a blueprint for male and female gender, however it is just that, a blueprint, you do not have to follow those rules. Two humans with the same gender can have completely different genitals and hormone balance. So it is not upto anyone to classify someone's gender apart from the individual themselves.

Pronouns are also at the discretion of the individual, it does help if pronouns do not contradict the grammar of the language used. Some people believe a person's right to a pronoun is more important than language. Some people believe language integrity is more important than someone's pronouns. 

One final point, our entire planet is filled with corruption and greed, many countries born of freedom are on the brink or tyranny and we're busy arguing about genitals, get your shit together human race.  Whatever your stance is, I think we can all agree, we have bigger fish to fry.

TLDR: Sex is based on genitals and hormones, which clasify your sex, gender has no rules and therefore only the indivudal can clasify their own gender, science cannot.

Edit: Corrected mistake in tldr (accidentally typed sex instead of gender)

The reason gender is debated is because many people aren't willing to accept as free flowing a definition as you are. 

Some people believe that sex and gender are linked and not entirely separate. Some people believe that gender is assigned rather than subjective (that which society decides your gender is it is, rather than you deciding for yourself). Some people believe your distinction between sex and gender, but believe that pronouns refer to sex rather than gender. 

So long as those (and others) definitions of gender exist, then there will be debate about gender. Not to say any of these definitions are "right", just that as long as they are prevalent, there will be debate.
