With a blood sample, a doctor can determine gender

I like the Green Bay Packers beanie. Nice touch.

That's in the original photo - I didn't add that.

Funny, I never noticed that.

You're confused, sex and gender are two different things.

This proved absolutely nothing other than:
1. He doesnt let the kids in his class to look at their own chromosomes.

2. "Biological sex is complicated" with that being the only information he really gives us.

3. your supposed to let people tell you "who they are" not go off of gender which might be too "complicated" to understand.

Also hahahhahaahah

I’ve already made an argument on this before so for the sake of time I’ll just put it here.

Females have two X chromosomes and males have one X and one Y chromosome which decides your "gender"

If you are a male then:
your body converts more energy to muscle, you have more red blood cells, you have larger hearts larger lungs and more muscle mass, higher testosterone, etc

If you are a female then:
your body converts more energy to fat, you have more white blood cells, your body produces antibodies quicker, higher estrogen and progesterone, etc

I will not mention the other obvious differences that we all know for the sake of NSFW.

This said gender isnt based on how you feel about yourself (which is quite literally what your "gender" system suggest). You can only be a man or a woman when your born which does make it a "lifestyle choice" if you decide to be a transgender homosexual etc.

To show what I mean by "based on how you feel about yourself" with these "genders" I will list a couple to make this point.

"Surgender: having a gender that is 100% one gender but with more of another gender added on top of that."

"Multigender: the feeling of having more than one simultaneous or fluctuating gender; simultaneous with multigender and omnigender."

"Colorgender: a gender associated with one or more colors and the feelings, hues, emotions, and/or objects associated with that color; may be used like pinkgender, bluegender, yellowgender."

"Vapogender: a gender that sort of feels like smoke; it can be seen on a shallow level but once you go deeper, it disappears and you are left with no gender and only tiny wisps of what you thought it was."

Gender is actually directly related to s** and how your body works and it’s incorrect to say it is not.

No they're not.

Whatever you say subgenius

;-D

I have heard of a few people were the test is inconclusive.

Get a better doctor.

The thing is in a small minority of the population, you get a XXY result or other anomaly, and then it isn't that simple. https://www.buzzfeednews.com/article/azeenghorayshi/sex-testing-olympians

Those rare types are mutations, anomalies. They represent a fraction of a percent of the global population.

You can tell the bias of the author of that article by this one sentence:

"Critics say these tests try to draw a firm line between the two sexes where none exists in nature"

There are stark, and distinct differences between the sexes.

So I'm right, but you're busy arguing against something I never said.

I'm arguing against something written in the article you linked.

"Get a better doctor." Doing one doesn't mean you're not also doing the other.
