> We shouldn't be charitable to racism, sexism, delusional religious beliefs, or fascism; they are too harmful to the world. In this case, you're asking me to be charitable to a sexist article whose author does not justify their credentials beyond being a professor of philosophy; perhaps they are only accidentally sexist here?

If author justified his credentials with more titles, it would be better? If he was a biologist, his paper would stop being sexist in your opinion? Why does it matter?

As for the article itself, it isn't sexist IMHO unless you believe that stating that the biological sex exists and in human case there are two sexes is sexist. If that's so then the most biologists I've met are jest sexists and I should probably call the police and denounce them as petty criminals.

You're right that author contradicts himself in the sentence "The fact that no species has evolved more than two biological sexes is also a puzzle". It's definitely a logical error on the author's side and is plainly wrong, but it's not the main point of the paper.

No, the entire point of critiquing the author's qualifications is to break apart the idea that, because the author is well-spoken, they are therefore correct or even reasonable. If the author had declined to publish a miniature biography beside the article, then I would not have said anything. I haven't, for example, examined the rest of his body of work; I don't have any predictions to make about what else he may have written.

> stating that the biological sex exists and in human case there are two sexes is sexist.

You got it! Sort of. It's not a problem to use the concept of biological sex, but it's completely wrong to say that humans have two biological sexes. The main problem is in the assignment of chromosomal configurations to sexual configurations; humans have a dozen or so intersex [0] configurations which don't fit neatly into binary gender theory.

And this has real-world consequences. There are many countries which have canonicalized various sorts of human-rights abuses based on the binary theory, mostly by establishing some sort of concentration camps for homosexuals. The author's writing forms a small but real brick in the wall of these camps.

> If that's so then the most biologists I've met are jest sexists and I should probably call the police and denounce them as petty criminals.

This is the error. It doesn't make sense to criminalize sexism, and indeed it's not criminalized in any jurisdiction that I know of. Instead, what's criminalized are specific deleterious pragmatic aspects of sexism: Sexual harassment, genital mutilation, conversion therapy, forced emancipation of trans children, human trafficking. When biologists are sexists, they are usually being reductionist as the author is doing, by minimizing and ignoring the diversity of the real world's biosphere; they are not directly advocating for the harm that is done by other, more hateful people, based on their reasoning.

Also, yes, my priors are that people are 99% racist, 80% sexist, 85% delusionally religious, and 20% fascist; this gives me a weak but steady belief that the typical person I talk to is, in some way, a sincere believer in deeply harmful and falsifiable cultural beliefs. I'm in the USA, for what it's worth; hopefully it's not like this everywhere.

So basically you make an attack ad personam because it is effective way to win the discussion. It is not enough to dismantle his argument, you have also to make him unreliable source of knowledge. For my part, I haven't noticed the little bio, but I know it's a common practice to show a short info about the author under his article. It's a two edge sword, some readers may be impressed, some may feel like you.

> but it's completely wrong to say that humans have two biological sexes

So I guess saying that humans have two arms and five fingers per hand is also completely wrong. You know that due to strange genetic conditions, some people are born with more fingers, etc.? Some people get Down syndrome due to an extra chromosome, but still it's correct to say that humans have 20 chromosomes. It doesn't mean that there are no exceptions and doesn't dehumanize those exceptions.

I believe you're oversensitive in this area, but I guess you already told me why.

It's all a matter of how wrong you want to be, and what information you want to use for deduction. If you see a humanoid approaching you, do you start with "that is a human (99.99% certainty)" or "that is a man or woman (98% certainty)"? I can see the use in the latter, but only here when quantified and compared to more generic alternatives.

I assume that you know about the facts that some humans have fewer than two arms, and some humans have not just fewer than five, but also sometimes more than five fingers [0]. In what way, then, do you hope to show that the facile versions aren't wrong? I think that what you're saying is that it is quite common for human genetics to plan for people to have two arms and five fingers. But it's not universal. We must distinguish between the two, because every time we make a universal claim about humans, we implicitly exclude the humans who aren't covered by the claim. Indeed, intersex folk, polydactyls, amputees, and folks with Down syndrome are all marginalized in our society, and all via this same mechanism of minimization and normalization.

Generalization is one of the main mechanisms making the communication (language) work. Otherwise one should probably treat every human as an individual, similarly to the Duns Scotus and his haecceity concept.

It's somehow related to the concept of overfitting, you acknowledge existence of the outliers but at the same time you may want to generalize them for the sake of the better generalization...

Who cares about karma. What's important is that your comments may encourage some readers to think ;)
