Well, frankly, I have no delusions that my caring will cause you to modify your behavior. So, I guess I don't care what you do in your private life. What I do care about is your unfortunate tendency to aggressively coerce recognition and acceptance of your chosen lifestyle. What I do care about is the fact that you will attempt to force my church to accept behavior that is completely antithetical to the beliefs we hold. What I care about is your obvious desire to subvert my religious beliefs.
If you consider yourself to be of a particular religion except for the fact you are gay, then just go ahead and start your own church where gay relationships are acceptable. Virtually all of the work will already have been done for you.
There are two components to marriage, a legal contract between you and your spouse and the state, and a covenant between the two of you and God. For the first, there isn't anything to stop you. Form a LLC with your spouse including some specifics about property and inheritance and you more or less have it covered. Go to your new church and hold a ceremony according to your "corrected" beliefs. But don't try to coerce my church into recognizing your marriage.
That's why I care.
The state should not be in the marriage business, anyway. The co-mingling of the religious and legal elements of marriage is an artifact from the monolithic church of Rome, which was above even Kings in its earthly power. Let the state enforce the legal contracts, and let the churches handle the religious aspects. And if you are an atheist the religious component of marriage shouldn't matter to you. Try exercising your rights instead of trying to infringe ours.
Very well said.
