Check out this wonderful autobiographical post on Darwinism and Gays by D. Stephen Heersink. I don't think I am spilling anything by giving his conclusion because there is so much great stuff in his post.
"Darwin is every Gay and Lesbian individual's HOPE for the future, for every individual "queer's" HOPE for diversity and pluralism, because Darwin's theories insist upon it. Can Queers not correlate the denunciation of GLBT and the denunciation of Darwin as having a related "associated basis?" Are you that dense? Are you "excluding the middle" of inferential reason? Reasons, invalid though they be, exist for the shared denunciation."
