Superficially it's a problem if homosexuality is genetic - if the difference between people's sexual preferences is genetic - because at least a pure homosexual would be unlikely to reproduce and therefore pass on the genes. So the first question you ask is, is it actually genetic, and the answer is probably to some extent yes.

Richard DawkinsTime and again, my sociobiological colleagues have upbraided me as a turncoat, because I will not agree with them that the ultimate criterion for the success of a meme must be its contribution to Darwinian "fitness". At bottom, they insist, a "good meme" spreads because brains are receptive to it, and the receptiveness of brains is ultimately shaped by (genetic) natural selection.
Richard DawkinsThere isn't [in new atheism]. Nothing that wasn't in Bertrand Russell or probably Robert Ingersoll. But I suppose it is more of a political effect, in that all these books happened to come out at the same time. I like to think that we have some influence.
