Don't laugh. Just as you support homosexual marriage others support bestiality and will one day demand the Supreme Court give them the same rights - for a man to marry his horse! And when a clerk of the court refuses to issue the marriage license, they will be accused of persecuting the horse and man practicing bestiality and once again - "the persecutor" will be thrown in jail.
Leviticus 20:15-16 commands, “If a man has sexual relations with an animal, he must be put to death, and you must kill the animal. If a woman approaches an animal to have sexual relations with it, kill both the woman and the animal. They must be put to death; their blood will be on their own heads.”
Deuteronomy 27:21 agrees, “Cursed is the man who has sexual relations with any animal.” From these verses, it is abundantly clear that, according to the Bible, bestiality is a horrible, unnatural, and abominable sin.
