Just now I discovered a brilliant new way to describe so-called Christians who would deny gays the right to marry one another. I found it in a letter in response to the Salon article "Gay Marriage in the Heartland", about Iowa's decision to allow gays to marry. The letter writer gave credit to Slate Magazine, but whoever came up with it is a genius at nomenclature.
So, these imbeciles aren't Christians, they're Leviticans. Call them that, to their face when necessary.
