I’m pretty certain laughing dog has nothing to learn from Emily about reproduction, which is the narrow use of the word sex as reproduction—when it suits her
Here's what he posted:
Since trees can male, female or both, the sex is not binary. Clearly you have been kicked in the head multiple times.
I'll bold the important part.
Sex is binary.

The categories male and female do not fully describe the sex of humans and some other species. Male and female do describe gametes.
Male and female do not describe gametes. Male and female describe the reproductive systems that have evolved to support those gametes. The gametes themselves are testes and ovaries.
About half of one percent of all humans do not biologically conform to the ‘ideal’ of binary male or female.
"Ideal" has fuck-all to do with it. There exists NO OTHER sex among humans.
Look, you just said you're a biologist, and chided me for providing accurate information. So, as a biologist... what other sex exists among humans? What evolutionary role does that other sex fill? How does their reproductive system function?
Look... humans have two eyes, which contain rod and cone light receptors, and which use muscles to contract and relax a lens which allows focus at different distances.
That's a true statement, from a biological standpoint, wouldn't you say? Now, we all know that some people have genetic mutations or errors that cause them to be born completely without eyes. It's rare, and it's a disorder, but it happens.
As a biologist, do you think it would be reasonable and appropriate to assert that "humans have two eyes" doesn't fully describe the number of eyes of humans as a species? Do you think it would be reasonable and appropriate
as a biologist, to assert that humans are a species that has a spectrum of eye numbers?
I mean, holy cow. You're essentially taking a hard-line stance to say that
as a biologist it's wrong to describe humans as a bipedal species, because sometimes a person is born without a left leg. At this rate, you're gonna make it impossible to accurately describe any species at all in any way, and you'll just tear down the entirety of cladistics and phylogenetics.
