The thing that earned Rick Santorum the rather unsavory neologism was the way he morally equated homosexuality to bestiality, pedophilia and wife-beating.
And to his mind, they are the same, because he sees them as abominations unto the Lord, and therefore, all things that we should outlaw as sinful and immoral.
He believes that we are all free to “obey God’s will”.
There is no arguing with people like that, all you can do is mock them and make them appear ludicrous, and associate their surnames to foamy brown substances.
