I think gay people should have just as much right to be miserable as the rest of us.

On a more serious level:
As far as religion and faith go, I'm not going to look down on those who practice and believe. That is because America is a melting pot of faiths and religions - not one is better than another. For this reason, no one faith should be placed on high and used as a reasoning and backing for laws of any sort.
An a-theist approach to governing is the best approach as it includes everybody and excludes none.
When it comes to gay marriage, I see absolutely no reason why two men or two women cannot be treated the same as a man and woman would. It is well within your moral convictions to feel that "homosexual marriage" should not be legal - whether for religious or other reasons.
With saying that I do not feel that they should be denied the right to decide medical attention for each other, nor should their property be kept from each other if something should to someone in the relationship, but all of these things can be taken care of by a living will.
Trying to sound as polite as possible (with such a heated topic, I'd like it to remain civil), America has tried the "separate but equal" approach. It failed in the past; it fails today.
For your statements, why should two men or two women have to jump through legal hoops just so that one can see the other inside the hospital or make medical decisions? Even with a living will, a living family member (even from one of those families that abandon their children for this) can come in at any time and trump that living will and put the partner out in the cold.
Families already do this with heterosexual marriages and sometimes win - the rate for homosexual "partnerships" being much higher. Sadly, I've seen first hand what happens when a god-fearing judge makes the ruling on such cases.
Marriage comes from the bible and it is stated that it is to be between a man and a woman.
In America, marriage is a legal institution. That is why there are people capable of marrying couples without a church. That is also why there are some pastors/preachers/religious figures who do
not have privilege to enter a couple into a legally-binding marriage.
My marriage, for instance, was void of religion and religious connotations.
However, if people want marriage to remain a religious institution, would it be fair to change all legally-binding marriages into civil unions and therefore let homosexuals partake in such civil unions? This would then end the separation between homosexuals and heterosexuals.
In the end, if my husband was blessed with female parts, I would love him/her all the same.
