As more and more gay people came out of the closet, the stigma of being gay went away. If gays are allowed to adopt, the stigma of having gay parents will go away.
How parents raise their children is reflected in how they treat other children. (I should know. My daughter got into a knock down hair pulling fight at the bus stop defending another child.)
I don't think we are giving these children enough credit. This teasing and scarring for life was always behind my Mom's reasoning that black and white peopel shouldn't have children. THINK OF THE CHILDREN!!
