Connor you've made it clear you hate adoption for a long time now. This isn't anything new. You seem to have this inexplicably negative predisposition towards it. Why? As others have pointed out, some people for whatever reasons are incapable of having children. Whether they be gay/lesbian couples, people who are infertile and thus unable to have children, or maybe they just want to love and take care of a child who was abandoned by their real parents.
The fact that you do not see an exception to your belief that "Adoption is all bad for reasons because I say so!" means you probably had some kind of negative experience during your childhood that made you feel that adoption is an exclusively negative experience for the child and involves some kind of ulterior motive with the adoptive parents. If you want to talk about that experience, I'll lend an ear.
