Is the movie "Horton Hears a Who" indoctrining our children to believe in things that don't exist?

I think it convinces children that abortion is wrong. It doesn't tell people to believe in things that don't exist, because the little people did exist. It's just that the other people didn't see the evidence, and wouldn't take Horton at his word. It's the same with abortion. Of course everyone knows that unborn babies exist, but they don't think they are human or persons. Well, a person is a person, no matter how small, or at which development stage they are in.
