This is silly.
Straight men can marry (given consent) exactly the same people that gay men can marry. Straight women can marry (given consent) exactly the same people gay women can marry. It's not a naive point of view...it is just a correct one. Whether it is worth talking about, I don't know. The fact also is that gays can not marry the people they want to marry...while straights can (given consent). But before the law, straight males are treated exactly the same as straight gays, when it comes to marriage.
Why you guys choose to make such a big deal out of it is beyond me. It's really just a thing you should say "Ah, yes, this is true, but the right for a man to marry another man, if he so consents, should be given regardless".
Especially you, Ordo. You said exactly the same thing Gav, Sym and I pointed out, it's an issue of freedom of choice FOR EVERYONE, but then you choose to make Gav appear as ignorant or childish, likely because he is a Catholic (and might very well be against gay marriage, I don't know). I think above all we should be fair, if the side that we are opposed to makes a valid statement, trying to deny it makes us but look silly.
[edit] Though I do disagree with Gav that everyone is equal. Women and Men can't choose from the same set of people. Therefore women and men are unequal, when it comes to marriage.
