You originally said "And children tend to do much better with two parents actively involved in raising them to adulthood, everything else equal." and "I would suggest that children should be a choice made by a man, and a woman together in mutual agreement whenever possible."
When it was pointed out that two women or two men could be the two parents who are actively involved in raising the children, your argument gradually morphed into "Lesbians have no ability to relate to male children in a way a dad can. Gay dads have no ability to relate to girls on their period for the first time."
This is called "moving the goalposts."
(And as an aside, you also said "THIS is sociological issues, and while not unique to Gay / Lesbian couples, affects all of them." Which is entirely untrue. Some gay couples have only male children, and some lesbian couples have only female children. And given the way in which such couples have children it is even pretty trivial to choose the genders of their children if they wish. I'm not saying they should, just that your argument that it affects "all of them" is totally unfounded.")
However to address those shifty goalposts, as far as i can tell you are basing this argument entirely on personal experience. I'm sorry if you felt your childhood was less than ideal because you didn't have a male role model, but that doesn't apply to everyone else.
I'm male and i definitely related far more closely to my mother than i did to my father, perhaps because my dad spent so much time at work. (He spent plenty of time with us during the periods when he was home so it's not like we felt neglected. I was quite happy with my childhood and as far as i know the same is true of my sister. However there's no denying that having to work to support your family means spending less time with that family.) My sister on the other hand was always arguing with my mom (and our mom told us that she always argued with her mom, and her mom told her that...) so it always seemed to me that she related much more to our dad.
Meanwhile i can't really tell any substantive differences between the son of my lesbian friends and the son of my heterosexual sister and brother-in-law. The first likes sports and video games. The second, last i checked, was into monster trucks and princesses. They're both _far_ more rambunctious than i remember being as a child (though clearly there could be some bias/rose colored glasses there) and both seem quite happy and well adjusted.
Maybe some differences will appear once they reach puberty, but i never had the "birds and the bees" talk with either of my parents. I learned all that stuff from sex ed classes at school and the internet, so i don't see why having a parent of the "appropriate" gender really matters. I honestly don't think it would have made a difference if both my parents had been women. Perhaps a girl would feel differently about having two male parents, but i can't really say anything in regards to that.
You say you think children deserve what's "best". How is not being born at all better than being born to parents of the "wrong" gender? Do you think any woman in a same-sex relationship who gets pregnant ought to immediately go get in abortion?
In short, everything i've observed has shown me that actual children of actual same sex couples can be just as happy and well adjusted as the actual children of actual heterosexual couples. That certainly isn't "proof", but it seems to me that it is a far more compelling argument than your theoretical opinions about people that you don't seem to have any actual experience with.
