Why ...always have a one-track mind and only think in such a monocausal manner?

Because there is a single causal principle at work; natural selection gradually improves functioning. Europeans who have been eating a carb laden agricultural low D diet, wearing clothes and doing without UV-B/ vitamin D synthesis several months at a time for hundreds of generations have had thousands of years to develop adaptations that would optimize circulating levels of 25-[OH]-D to enjoy maximum vigour for the longest time. That would translate into evolution's currency of reproductive success. Europeans are the descendants of those who were the best adapted, something that's as common as D insufficiency is claimed to be could only be due to a new factor or it would have become vanishingly rare by now; unless of course it is a pseudo-disorder.
Wifezilla's point about Somalis has something going for it, in theory those adapted to African sun would be far more likely to have problems. However if he'd bother to read the information I have linked to Vitamin D and homeostasis he would know

single-dose, whole-body UVB exposure black subjects had distinctly lower serum vitamin D3 levels than whites, but differences between the two groups narrowed after liver hydroxylation to 25-OHD and disappeared after kidney hydroxylation to 1,25-(OH)2D. These findings suggest that there is a compensatory mechanism whereby, in the presence of vitamin D3 suppression by melanin, the liver and kidney hydroxylating enzymes are activated in tandem to ensure that the concentration of the biologically active 1,25-(OH)2D metabolite is normalized and kept constant regardless of ethnic pigmentation (Matsuoka et al., 1991, 1995).

Explaination for higher rates of autism is not hard to come by A mysterious connection: autism and Minneapolis' Somali children

A Harvard team funded by the National Institute of Mental Health studied Middle Eastern families in which cousins had married each other. In five of those cases, children showed genetic defects linked to autism. Many Muslim Somalis marry their first, second or third cousins, putting them a category suspected to be more at risk
