Hmmm . . . I share the commentator's exasperation with the abstract.
That the study would equate ->-bleeped-<- with homosexuality indicates that academia still has a way to go in recognizing who we are. Of course, we're dealing with sociologists, who are supposed to approach studies with fewer preconceptions than the rest of us, but it seems to me the methodology may be flawed if the conclusion is that homosexuality is genetic and not resident in the limbic system and that it is "expressed" as ->-bleeped-<-.
And that the continuation of homosexuality is propagated genetically runs counter to everything we as progressive people understand about both the nature of homosexuality as well as that of transsexualism.
