Newt, if you're intellectually honest, you will have to admit that just as single parenthood was once frowned upon and then not, and gay coupling was frowned upon, etc, etc. so can things change to include polygamy and incestual marriage; and even animal love. Why not? Are you such a prude that you can't even imagine it being the norm in our society? And why so averse to delve into the core of the issue, as to it's potential consequences on the cohesiveness of societies foundational institution, the family? Is that assertion of mine offensive to you? If you disagree that a solid family is not priority one for a society (including but not ideally between gay couples. The issue first, of course, is stability and care.) why?
