Do not fund lines of thought where the harms outweigh the potential benefits, and/or where ethical commitments are violated.
That policy is neither particularly strong or particularly uncommon. It's the guiding principle behind IRBs, which are pervasive. (In fact, as Horgan points out, one of the primary motivations for IRBs was racist scientists conducting downright evil experiments on black men.)
There are two components to this analysis.
First, do benefits outweigh harms? This is easy because there are no benefits. Suppose there is a correlation between race and IQ. What non-evil thing, pray tell, would you have us do with that knowledge?
Second, are there any ethical violations? Also easy. Racial superiority theories aren't "political outcomes that I don't like." They are fundamentally Evil; for god's sake, this is one of very situations where the motivation behind Godwin's Law doesn't apply.
