Fundamentally Different

"Promising equal treatment to some is fundamentally different from promising equal treatment for all," Moreno said. "Promising treatment that is almost equal is fundamentally different from ensuring truly equal treatment."

Far and away the best commentary I've seen on this has been from rm. Excerpt:

The entire situation, that this is even something we're debating as a nation, is so completely irrational, I kinda can't deal with it. It is only rational if the debate is framed thusly: "are gay people human?" and until people who are anti-equal marriage are willing to make the assertion that gay people are not, in fact, human and as such should not be allowed to enter into any legal contract or business relationship, I have even less than zero patience for their arguments.

Say what you mean and mean what you say. Even if I find your personal "deeply held beliefs" bigoted and offensive, I'm peripherally willing to acknowledge you as a thinking person if you at least have the nerve and the intellect to stand by what you really mean.

Exactly. Exactly that.
