Genes within a single species' gene pool follow a Poisson distribution because they are randomly permuted [1][3][4], assuming the pool is large enough. This means that often, some genes will be popular for no good reason; that is, these popular genes are cosmetic. When, for example, most people in the world follow one of several popular skin-coloration patterns, that does not therefore imply any sort of fitness function is selecting for skin colors, because the null hypothesis that they are randomly permuted has so little problem explaining how they could arise without any effect on fitness.
These questions aren't dangerous because they somehow subvert existing institutions, but because they're a direct introduction to ethnofascism via eugenics. We should roundly not just reject them based on empirical observations and data, but also based on theory and modelling; this is because we can then use contraposition to flip around various deductions. For example, people often ask whether "race" affects "intelligence" and point to survey data which shows correlations; using contraposition, and understanding that "race" is a social construction, we can refute the idea that "intelligence" is innate and suggest instead that it is tied to socioeconomic status or quality of education or other confounders.
I would end with a question: What observations and data, exactly, are you looking at? What conclusions have you drawn? Can we use contraposition to flip around any of those conclusions and find deeper or simpler truths?
