I am certain that Dennis Prager is distilling something that he wrote or said somewhere else on the internet.

Not
to say that children raised by gay parents or a single parent are
defective. They are not. IN THE AGGREGATE to say that it is best to for
a child to have a mother and a father is now considered an act of
bigotry. Do you understand how the left has distorted life. That to
say that it is best for a child to have a loving mother and father is
now to be considered a racist like bigot. Think about it!
