A Boy's Tail

Set on the planet Equus, where the dominant species has evolved from horses instead of primates, the civilization is much like Earth, except that there is but one theocratic government. Being descended from horses, yet similar to humans in body construction, the inhabitants have the head, hands, and feet similar to horses, but only the adult males have a tail, which, like human facial hair, grows in at the onset of puberty. All tails are white, except for those who are attracted by their own sex. Their tail grows in brown.
Tyler is your typical teen, but a late bloomer. When his tail starts to come in, his world is turned upside down. Through the trials that are familiar to many gay teens on Earth, he experiences just what damage religious prejudice can do, because of the mistaken notion that being same-sex oriented is a choice. Just as Tyler becomes smitten with Joey, religion clashes with science and the whole of society is rocked to the core by unspeakable violence. Will civilization survive?

Self-identified Christians, by drawing parallels, should reconsider their religion-based homophobia, when true Bible scholars know that Christ said nothing of the kind.
