I think you'll all agree with most of them! McSweeney’s Internet Tendency: List: Arguments Against Gay Marriage.
It's when you have one or even two whores who get married, keep it overly open, and are doing it to make it look legit and feel like they belong to a more accepted institution. Sometimes, that's very transparent and, to me, looks more like a joke than a marriage. Remain BFs or GFs if that's the case.
Those are bad reasons to marry anyone, regardless of orientation. (Except for Tim, being a whore isn't necessarily a bad thing! :lol: )
