The other thing that pisses me off about arguments like these is that they are so self centered. Since when do we need to directly benefit from something in order to see the value of it? I don't have children, yet I still vote to support education.

Participation in democracy is not about reaping personal rewards, it's about creating government for the sake of the people.

To say that you can't vote for someone's right to marry just because your personal politics can't find a place to reap benefits is at best immature and at worst, Republican.
