To be brief:  it is one of the founding principle of this nation that one has the right to be happy. (That comes of course with the price of not making others unhappy.)  In making single sex marriage legal, one has to look at all options and answer these questions…

Is is unfair to allow heterosexual couples rights not allowed to single sex couples?

Yes, it is unfair.  Anytime there is a double standard, … it is unfair.  (That is actually the proper definition of the word unfair: ie. employ a double standard.)

Will single sex marriages cause any harm to anyone?

No, it will cause no harm.  Whether someone two counties away lives in a civil union or a legally sanctioned marriage will not affect me (or you) one way or another.

There you have it.

Allowing Single Sex Marriages will repair an injustice and will not cause any harm when it is done.

Meaning the only two reasons to vote against it, are because you purposefully want to be unfair, … or you purposefully want to harm someone.

Passing this is a no-brainer.  If we are going to start listening to Christian fundamentalists, then we had better be prepared to listen to Islamic mullahs, Jewish prophets, as well as  every Wikkim candidate for office… Sure they have a right to speak, but we have a bigger right to ignore them.

Passage of this is a no-brainer because it corrects a longterm unfairness without hurting anyone in the process….
