As I have said repeatedly, I don't doubt that gay couples can create loving families. I don't doubt the children are well-adjusted. I know better than to lump gay families in with single-parent families, statistically.
But I've seen enough good fathers to know, that in addition to good mothers, they are important. "Give me research!" you say. Research that a dad is important? Do I need research that a mother is important too?
Last night around our dinner table, the men were talking about pinewood derby races, sports cars, and planning a guy-trip out to a ranch to go shooting. My sons loved it! Somehow a trip to go shooting with their mom wouldn't be the same. My husband was a scoutmaster for a while. He took our boys camping in snowcaves, canoeing, deep-sea fishing, eating gross stuff they cooked over a fire, and much more than I can remember. They've gone on extended bike-rides, snow skiing down suicide runs, white-water rafting and windsurfing. Now it's possible I could have pulled up my bootstraps and done this stuff with them, but I wouldn't have loved it like their dad did, nor been any good at most of it. He has taught them woodworking, and repair skills that he learned from his dad, who learned it from his dad. And several times a son would seek out his dad, to quietly, privately talk about a concern, something he couldn't talk with Mom about. When my youngest son left for two years to be a missionary in a remote land, his older brother (who had previously been a missionary) told him: "When you have hard times, write it to me or Dad. Don't tell Mom, she'll worry too much."
This is my research.
I'm the one who has dinner ready when they get home, and keep the home a place to want to come to. I remember the birthdays, write the letters, create the Christmases, and all the other holidays, keep the drawers stocked in clean clothes, keep the fridge stock in food, and give advice on their girlfriend problems--"because they don't understand women" as they say. My job is to kiss the hurts and shed the tears with them. I'd much rather be home doing the laundry than sleeping in a snowcave and am glad their dad is willing to do it.
I also get to melt with joy, when I behold my children, now adults, each firm in who they are and their importance in this world.
My sons have learned to treat their wives respectfully, because of how they saw their dad treat me. My daughter has chosen a husband who also treats her respectfully because of what she learned at home. To grow up with a loving, involved man for a father is priceless for a child. It's a legacy they pass down generation to generation. They grow up knowing first hand that men are good, compassionate, gentle, strong, wise, lovable, capable, a little clumsy sometimes, but irreplaceable. Just as women are irreplaceable.
