Hospitaller,
Those who hold the religious idea that marriage should be “one man, one woman,” have a right to their religious beliefs. All churches are free to choose who they marry as their religious doctrine dictates, but every American should not be subject to their religious laws. One of the founding principles of this country is the idea of religious freedom. We should be all free to worship, or not, as we choose. This idea relates to the application of religious laws as well. A person cannot be held accountable or persecuted by the government if they choose not to follow the laws of any religion. The founding fathers of our country understood this. Thomas Jefferson wrote in 1776, "We have no right to prejudice another in his civil enjoyments because he is of another church." Meaning, a person should not be treated unfairly by the government if they hold differing religious beliefs. By not allowing same gender marriage on the grounds that it goes against the religious doctrine of some, same gender couples are in essence being treated unfairly by the government for not following a religious law.
So, I don't care what your religion says about homosexuality or same sex marriage. Nor should I because I am not of your religion and I shouldn't be forced to follow its laws or dictates. My government should extend the same rights, privileges and obligations to me that it extends to you, plain and simple. You don't have to like it, but as a freedom loving American (if indeed you are) you should support it.
