One of the most popular arguments against gay marriage is that if we legalize gay marriage it’s a slippery slope to legalizing polygamy and beastiality. My response is: so what? People who are in favor of gay marriage are far too quick to dismiss these other forms of non-traditional marriage.
Can anybody think of a single reason why polygamy or beastiality is bad other than “it’s unnatural”, “it’s disgusting”, or “I hate it”?
Remember, we should never be legislating taste and if somebody wants to have sex with his cow who are we to judge? If somebody is in love with two women, or three, or four, or five, who are we to judge them and say they can’t get married?
There’s an argument that it’s dangerous: diseases can be transmitted between humans and animals, and polygamous relationships might lead to bad parenting. If disease is a problem practice safe sex, and polygamous marriages don’t lead to any worse parenting than “traditional” relationships.
Let’s also remember that the law will neither stop nor encourage this behavior. Somebody crazy enough to have sex with a cow is going to have sex with a cow regardless of whether it’s legal. Somebody in love with two women is going to sleep with both of them regardless of what the law says.
So, I ask you: if we’re going to legalize gay marriage, why not legalize other non-traditional forms of marriage along the way?
