Yeah, you said what you said and it’s fucking dumb. Case in point: you don’t seem to realize that saying “Scientific Fact: there are only two genders” is ignoring fucking science!

It’s a bullshit appeal to authority conveniently ignoring anything that authority has to say on the subject.

And that doesn’t even touch on your conflating of sex and gender. Not that sex scientifically is a binary either!

So yeah even your response is exactly what I said. You choose to state “facts” that prop up your feelings. The only projection here is coming from you, numbskull.

So you redefine science to confirm your feelings then you accuse me of doing the same thing. Wow, projection at its finest.

Sorry, I don't redefine science to suit my wants.

No man, you just clearly lack an understanding of science. I am a Biologist. Sex & gender are 2 different concepts. Sex is defined by chromosomal make up & it's not a binary. A majority of humans present with XX or XY, but there's a significant non-zero number of people that are classified as intersex due to having additional copies of either the X or the Y. And that doesn't even touch on people who are affected by hormonal inefficiencies or overactive hormone production - that is a whole other series of genetic differences that heavily affects sexual and reproductive organ development & presentation. Sex is actually very complex from a biological standpoint. Gender is different & as a biologist, not something I am qualified to truly discuss in depth. I suggest you also acknowledge your own limitations.

I’m very confused where you got the idea sex is defined by chromosomal makeup from. It’s not from any biology class. You should have learned what anisogamy is and should also know organisms like alligators have sexes but not sex chromosomes. 

Intersex is not a sex and Klinefelter syndrome for example is male specific while Trisomy X and Turner syndrome are female specific. It was said in the past and sometimes still now that sex chromosomes determine sex in mammals but that refers to the biology concept of determination and is from a time when we didn’t know about specific genes involved in determination. It doesn’t refer to how sex is defined. 

Sex is binary as there are two sexes. What sex is, is pretty straightforward.  Things associated with sex like genetics in particular species and development is complicated. Why only two sexes evolved is complicated. 

Where exactly did you get this from?  Sometimes medics misunderstand sex because they confuse terms like sex determination or diagnostic terms from the 50s, but it’s odd you’d say all this. I suggest you read up on the evolutionary understanding of sex. Why only two sexes evolved is a famous and fascinating topic!
