Exactly the same way that you “prove” you’re straight when you marry a woman. ie Not really necessary.

I'm thinking that marriage isn't and never was defined as a contract between two "straights" but rather, between a male and a female.

Well, there you go. Gay marriage will be defined as marriage between a man and another man.

The marriage in my previous post should be “marriage”.
