Okay, so a science fiction writer I've never heard of, let alone read, posted a nasty homophobic rant on his LJ because a certain SF television channel has recently made a commitment to include more portrayals of LGBTQI characters. He has since taken down the rant, but a Google cache copy still exists (because the Internet is forever). If you want to read his outpouring of vitriol, go for it. If not, I don't blame you.
The point of this post is actually a lovely open letter in reply to said outpouring of vitriol. Hal Duncan (the writer of the open letter) has written his response with sufficient detail that you don't really have to read the original post to understand the open letter. Mr. Duncan has also written with sufficient eloquence and marked mastery of irony that the open letter is a joy to read even if the sentiment were not something I heartily applaud.
Hal Duncan points out, amongst many other excellent points, the incredible cognitive dissonance of the argument that homosexuality equals the sexual abuse of children, incest, or bestiality.
So go forth and read. Please.
