I greatly appreciate you taking the time to find things, it displays a good will and charitable nature that's often lacking in the world. :)
That said, I have done a fair bit of googling and for various reasons, which would be too much of a digression to go into, have found most of those kinds of resources unsatisfying (e.g. the idea that differences are only skin deep is trivially refutable by racists). By possible coincidence I've already looked at most of the resources you linked (e.g. Sapiens and Uncle Tom's Cabin) and the HBDers still make a more convincing case. And I think this is mostly because while the HBDers can easily read the arguments of anti-racists and come up with counters, anti-racists are not even aware of the content of HBDer stuff and so cannot argue against it.
I think the censorship of racist thought (and other outside-Overton-Window thought) has indirectly lead to anti-racist argumentation weakening due to lack of understanding of what their opponents actually think and argue.
What you are describing isn’t a situation of refuting arguments. If I tell you that you can’t find the resources you seek because the racists have bugged all your devices and are constantly messing with your search results and reading material, I wouldn’t refute your argument. I would simply be ignoring reality or outright lying. That’s the reason why it’s so easy for a racist to come up with a counter argument to “turns out we are not genetically different): their argument needs only to appeal to a feeling, not be rooted in fact. In fact, the speed with which they come up with counter-arguments indicates mental gymnastics more than knowledge of the subject. Arguments for racism often center around specific “self-evident” truths which if you examine closely turn out to be simply circular arguments. As an example, one argument is that black people commit more crime than white people. If you look at certain statistics a certain way, you could come to that conclusion. But this ignores certain facts. For example, crime is much more strongly correlated with socioeconomic status. A poor white town is going to have just as much crime as an equally poor town occupied primarily by any race. But because white people got a bit of a head start in the US (as in were not bought and sold as property and not worked to death against their will), the median income for a black family is lower than for a white family. And of course keep in mind that most white collar crime is committed by white men who make up the majority of the C level at most corporations. We rarely prosecute that kind of crime even though it can be a lot more damaging (as in murder of one person means a murder charge. Dumping toxic waste into rivers that leads to hundreds of thousands of birth defects and genetic dresses is “white collar” so we fine the company and fire the exec, but nobody goes to prison).
Look closely, and you will find inconsistencies in these arguments. Oh, sure there are plenty of them but none of them seems to really hold up to scrutiny. Few will cite scientific studies (some will go as far as saying that science is censored so you shouldn’t trust it which is an obvious red flag for someone making shit up), and ones that do often misinterpret or misquote it. If you’d like we can try it out: find the best written argument for any of these points of view and we can together break down exactly where the lies and fabrications are.
