The human biodiversity crowd aren't white supremacists. They claim that different races have different average IQ scores and that these scores are meaningfully correlated with intelligence. These first two claims are extremely well accepted by the relavent fields. They further claim that these differences are largely genetic which is much more controversial but strongly suggested by twin studies - nonetheless this will be settled by cognitive genomics soon.
They do not think white gentiles are the most intelligent race. Rather what they claim is Ashkenazi jews are the most intelligent ethnic group with an average IQ of 115, followed by Hans Chinese,high-cast Indians and descendants of the African Igbo tribe at 107, followed by white gentiles at 100, hispanic whites at around 90 and African Americans at 85.
Their claims are descriptive not normative, are not flattering to white people, show many ethnic groups (including some African tribes) have much higher average IQs than white gentiles, and the fact that Ashkenazi Jews are found to be the most intelligent doesn't seem particularly white supremacist.
