You are kidding, right???
A parent, even foster parent, has a responsibility to raise the children in their care in the most moral and positive manner possible. OF course, no parent is perfect, but placing a child in an extremely immoral setting such as a homosexual or pedophile home is not exactly thinking of the best interest of the child.
But of course, the homosexual apologists say that there is nothing wrong with being "gay". That way they can continue to spread their cancer until the public accept it. Notice I used the word "cancer".
