(Disclaimer: This is an unabashed opinion piece, sociopolitical in nature. I care passionately about this issue but stop right now if your blood boils at the idea of same sex families.)
Human sexuality is brilliant in its complexity. I do have faith in credible science and I am fascinated with the relatively recent research in sexuality. Research suggests that aspects of human sexuality are essentially based on a continuum. For example, the breadth and depth of human sexual appetite can be laid out on a continuum from a very limited desire (or even no desire) to a much more voracious appetite. Placement on the continuum is individual and normal. Control of the appetite can be problematic but that does not take away from placement as individual and normal.
In the same way, research suggests that sexual orientation is not a choice but rather is one part of who we are. Sexual orientation ranges from exclusively heterosexual to exclusively homosexual and the range in between allows for all blended possibilities. If we assume that orientation is not a choice (and I do), then I cannot understand what issue there could possibly be with same sex partnerships. What possible impact could a same sex partnership have on my heterosexual marriage? If these two people are attracted to each other, what possible business can that be of mine? If they love each other and want to bring that love to a new level by parenting children, how could this be a problem? In fact, if they want to have a child, there has to be more thought than with heterosexual relationships. After all, pregnancy is not an accident with homosexual partners. Speaking as a professional who works daily with plenty of children who are growing up in dysfunctional families - in part, I suspect, because their conception was a "surprise" - I am often impressed with the strong and steady parenting of my two dad and two mom families. Something about the planning and thought that went into becoming families makes for stronger families.
In the interests of keeping this post short, I simply want to ask: why, in these tumultuous times, would we, as a society, deny anyone the opportunity for family ties? I don't understand how people can be so judgmental and unkind to other people who simply want to create family as they see it. If you think you have an answer, I urge you to respond. I genuinely want to know your rationale.
