Gay marriage should be legal in all states.
"One day I was at subway ordering a sandwich. I noticed that the person in front of me was ordering a completely different sandwich than mine and it made me very angry even though this effects me in no way whatsoever."
This is what those who are completely against gay marriage sound like. Religion may play a factor in this in some ways. But as a wise man once said, "There could be a giant tea pot circulating Neptune, but who am I to say it does or doesn't exist if I haven't seen it?"
Why should someone make choices for others when not even knowing them? Why should they control who they get married to? You don't want to let them effect you? Then let them be who they are.
