This outrageous ruling reminds me of the Dred Scott decision before the Civil War - a ruling that helped set it off - that declared that "Negroes" have no rights that a "white" person is bound to respect. It is a stake in the heart of what's left of our democracy, and can't be allowed to stand.
What's next? Corporations can sue for slander? Corporations get to vote in elections? Corporations can serve on juries? If corporations are "persons" that would be logical!
We shouldn't need a constitutional amendment to make clear that corporations are not persons, but apparently we do - so let's get to work and pass one!
