You must be aware there's a crucial difference between saying group x is *superior* to group y and saying that group x and y differ (on the average) on certain traits.....right?

Nope, that's a meaningless delineation in this case

Not clear what you're saying. What it seems like you're saying is, 'yes, but to prevent abuse by white supremacists, we have to deny any possibility of there being between-group genetic differences'.

No, I'm saying in this instance the differences are being implicitly tied to supremacy and are used to justify unequal treatment and outcomes that results in the continued suffering of marginalized groups

You're replying to literally no one when you talk about people claiming no group differences.

You need to adjust your approach then to 'group differences ≠ superiority, and the existence of group differences does not entail we treat people differently'.

Premising moral egalitarianism on the assumption of biological egalitarianism is dangerous. The two must be separated.

That chart is purely correlational hope this helps

No you see, when you take an unreliable value and correlate it to an unreliable value you get very strong causation actually
