I’ve never been a proponent of same sex parenting, especially of adoptions by single gays or same sex couples. I have always believed that children need a mother and a father in accordance with God’s design. But not only does my religious worldview bias me against same sex parenting, my professional experience has reinforced my bias.
I have seen too many horrendous examples of abuse linked to same sex parenting. My earliest expample was a homosexual fence (someone who facilitates the criminal redistribution of stolen property) who adopted a young boy who he turned into his lover. As the boy aged he trained him to become a world class burglar who would steal from the super wealthy in places like Palm Springs, Palm Beach, Boca Raton, etc. and then sell the loot using his “father’s” fencing connections.
Of course, there’s also the most recent example of the two Australian men (about whom I’ve already written) who adopted the Russian child, turned him into their own sex toy and then passed him around to international contacts for their “enjoyment” as well. All this before the boy turned 8.
While it’s true that heterosexual parents can do things just as terrible, and, conversely, that same sex parents can be wonderful and loving, I think this most recent study points to same sex parents generally being much worse by a significant margin.
