Science and reality exist separate to your ethical constructs, and there is scientific evidence that proves it.
You view the world as a two sided hypothesis. Either nature or nurture with nature being racist so nurture is better. But you are aware that this isn't true on some level. You know that genetics influences differences in behavior between men and women so much so that men and women across the globe can be fit into certain behavioral stereotypes that are sexist to talk about but at the same time exist as a permanent part of the fabric of reality. Anecdotally it is literally impossible to ignore the masculine behavioral traits of a trans woman because the genetics influencing behavior are so prevalent.
That's not evidence however. Let's not get into that because anecdotal arguments can become circular: When I present an example and you rewrite reality so that it fits your ethical world view or vice versa. Let us consider scientific studies. Is behavior caused nature or nurture or both? Obviously both, but let us see what happens when we control the nature part by only looking at twins or triplets separated at birth. What are the behavioral differences?:

I have long discovered that there's no such thing as a "mic dropper" the extent that humans will go to bend the evidence and examine improbable possibilities to maintain their ethical and moral world view is extensive. A logical argument will not convert a christian to an atheist and it will not change you. What follows from you, if you read this, is a long and involved break down to discredit my evidence a reexamination of the context from biased angles until you use the logic to construct a universe that fits the world how you see it rather than the world as it truly is.
The bottom line is: genetics made your brain therefore it influences your brain and in turn, your behavior. If such genetic differences exist between twins and between sexes then it must exist between race.
And keep in mind... never ever did I say environment is not a major influence for behavior. I never said otherwise i am only saying that to ignore genetics and say that genetics do not influence race is scientific folly and irrationality.
