Liberal democrat scholar defends marriage between a man and a woman

David Blankenhorn is a very highly respected family scholar on both ends of the political spectrum. He weighs in on Proposition 8:

For me, what we are encouraged or permitted to say, or not say, to one another about what our society owes its children is crucially important in the debate over initiatives like California's Proposition 8, which would reinstate marriage's customary man-woman form. Do you think that every child deserves his mother and father, with adoption available for those children whose natural parents cannot care for them? Do you suspect that fathers and mothers are different from one another? Do you imagine that biological ties matter to children? How many parents per child is best? Do you think that "two" is a better answer than one, three, four or whatever? If you do, be careful. In making the case for same-sex marriage, more than a few grown-ups will be quite willing to question your integrity and goodwill. Children, of course, are rarely consulted.

How many of us are well-prepared to clearly enunciate our beliefs on this issue? I, for one, need to be better informed, with a more developed and supported position that I can actually defend.
