All the 'unpleasant truths' you list seem to be facets of a single underlying issue of genetics. I consider none of them particularly shocking, especially in the weak forms you use there. Damn near any observable fact related to a given person will 'convey nonzero information about their their [sic] social status," so if you're going to use this persona to say what you otherwise couldn't get away with, how about you fill out your theory with some policy suggestions, or at least more specific predictions?
