But that is precisely the comparison that gays insist on themselves, when they make their assertions about the wholesomeness and kid-friendliness of gay parenting.
Why bring in a third model for comparison, except to give gay parenting an easier standard to measure against? Patrick Moynihan called this constant liberal practice (or "ruse", better), "defining deviancy down".
That is what the whole marriage debate -- initiated by the homosexual political crowd -- is about: Defining deviancy (theirs) down, by disparaging normal heterosexuality in all its expressions.
I'm a big believer in telling the truth - right to their faces.
The data shows that Gay couples are INFERIOR to married couples when it comes to raising kids. That's the truth ...
The secondary study, the "fair" study; would be to see how Gay couples measure against the Fostercare or Orphanage programs - because if they are inferior here too; this makes a great case to deny allowing gay couples to adopt kids, doesn't it?
