A Christian marriage is a covenant between a man , a woman and God...in the case of the elect of God ..we do not NEED the state to regulate our marriage.
As I was writing this it occurred to me that probably no other civil contract is treated with as little respect nor so often broken.
My concern is always for the children. I have become much more a libertarian in my old age..I feel little desire or need to control the lives of others, in any way. The exception is helpless kids..
The state has an interest in minors..for that reason the "Domestic Partnership" idea is troubling..kids could end up with many many "mommydaddys " to visit..because the state says they have an "interest" in them..imagine the possibilty for abuse..
Other than that I do not care what they call themselves
As you know, my own view is that there should be a "high wall of separation" between the Parents' authority over their children, and the "interest" of the State... a sacrosanct "don't tread on me" realm of parental authority, to be breached only in cases of outright Parental Abuse, etc.
As for Adoption, there really isn't any "libertarian dogma" on the subject of which I am aware and I tend to favor the formula of assigning Adoptive Preference to the extended biological family, in order of biological relation (this is what I call the "Braveheart" formula. I also happen to view this as the Biblical formula; correct me if I am wrong).
Admittedly, such a biological Adoptive Preference would create a situation in which Adoption by Homosexuals would be relatively difficult and uncommon (with the exception, I guess, of the occasional "gay uncle" who is the closest surviving relative); but I think I can live with that, even if the lavenders can't.
