I bet I am way older than you!
Yes, studies come and go, and they are often biased, including the ones that favor the mother/father dynamic.
In this day and age we are seeing so many different family make ups, that I think it will be shown that all are viable ways of raising children (and not just the exceptions).
War, of course, will always be a terrible thing for children...but, not at all comparable to gay marriage...my goodness.
I'm sure we could argue this until the cows come home, but will probably be pointless, as I think we each hold strong opinions on this subject. It's not one of my favorites to argue with friends. It is a very sensitive subject.
The world is changing on this issue, though, and I am very glad to see it. So much harm has been done to people (and kids!) who are same sex attracted, it makes me beyond sad to think about it. I pray that things will continue to improve and they will not bear the stigma that has been imposed on them in the past.
