He's already argued that there are loveless hetero marriages."the person they love" seriously?
Give me another law that changes based on what someone wants.
Here's the dealio: For every single point made in arguing for gay marriage, the exact same argument can be made for unlimited plural marriage.
Come to think of it...all those arguments apply to hetero marriage too - OMG - why have ANY marriage?
If you take the word "government" out of it, then exactly right. Government is so intrinsic to liberals you just can't imagine something existing without government, can you? Why cannot there be marriage with government left out of it? Why is that so impossible to fathom?
