I am pro-life because we know the unborn are alive, because they’re growing. We know the unborn are human because they have human parents, and I think human beings like me and you are valuable.
In fact, I think all human beings have an equal right to live, because they all have something special in common: they’re human. That’s why racism and sexism are wrong. Racism is wrong because it focuses on a surface difference that doesn’t morally matter and ignores the thing we all have in common, which is the thing that does morally matter: that we’re human.
