This was the Supreme Court that was supposed to tell us that fetuses were persons, or, at least, to permit states to decide that fetuses were persons. Instead, they decided that corporations were persons. Of course the very idea of incorporating involves your not being treated as a person in at least one important sense; LLC means limited liability corporation, which means that people can't go to jail for what the corporation does.
In the present political climate, conservative Republicans always get the part of their agenda done that benefits the big corporations. Fetuses don't make campaign contributions. Corporations do.
