Ha ha haaaaaaa

there's a recent paper about the statistics involved which suggests that there are issues with Blanchards papers on this, but some of the issues they raise are questionable. for example, in one of them they question whether counting hetersexual mtfs as "gay" for the purposes of the calculation is valid, which is somewhat subjective. even they agree that there is some contribution, but it's obviously not determined at birth, non older brother twin studies don't show a 100% overlap of sexuality in separated twins
