This is an ad hom argument, which is a fallacyThe second link is the Union of Catholic Bishops... what do you suppose their stance is?
This report also discusses the differences between children living in two parent homes where one was not the biological parent and children in single parent homesThe third promoted the benefits of children living wit their biological parents (kids who grow up with their married biological parents have a higher rate of religiosity in adulthood, dontcha know)
So one out of fourThe fourth article is a WaPo article asking whether we are overestimating the benefit of marriage to children
You are misdefining the word "intact" to include "biological" when the article does not say that.The fifth in an article at the Atlantic that reports on the benefits of intact families (married biological parents)
Even if all of the links were for children raised by both biological parents, other studies have shown that the children of same sex married couples do just as well as those raised by both biological parents.At what point does this start being a point in your favor? Link six and seven.. hmm.. nope. More talk about intact families.
I thought you had a chance with the 8th link but that Princeton site only said that there is no empirical evidence for the benefits of gay marriage for children...
And then there are the links that come up if you click on the link at the bottom of the page
