But I think one thing that ought to be pointed out is that the immorality of abortion doesn't hinge on Margaret Sanger's character; if it turned out we were wrong and that the PPFA spin on Sanger were somehow correct, however far-fetched that may seem, that wouldn't at all alter the fact that 'abortion' is the murder of innocent humans and ought to be outlawed as such.
You are absolutely correct, of course.
