Marriage Is More Sacred When It's Equal

Would you buy gas at a gas station with a sign saying "No Gays Allowed!"
Well, maybe it was an emergency; maybe if you had no choice.
But if you had the choice between two gas stations, one with the sign and one without, you'd go to the one that doesn't discriminate. You know you would; you might not be comfortable around gays but you're not a jerk.
So why is marriage different?
Why would you want to be part of an institution that says, "No Gays Allowed!"
Obviously, because you had no choice. The urge to marry is very strong, and no-one should be without the right. Up until now, you had no choice: you and I had to have a marriage based in part on inequality.
But now you have the choice. Wouldn't you go with a marriage that is not founded on discrimination?
Of course you would.
Because you're not a jerk.
