Person hood is still unrelated to Speech. It has no bearing. It is a tangent.
I'm sorry you still don't get it. Only people enjoy individual protected rights under the Constitution. Not plants, not animals, not objects tangible or intangible.
Actually, Intense is right. Corporate personhood is relatively tangential to this particular case. None of the justices' opinions in this case, including the dissenting ones, hinged upon the issue of corporate personhood. It was whether compelling state interests (not having our political system entirely controlled by corporations) overrode the free speech exercised by corporations. Based on precedent, corporate personhood and money as speech were just granted for this case, they weren't the element in dispute. I'll always tend toward the free speech side and take an absolutist approach to the First Amendment.
That's why I prefaced that comment with "Beyond that," Corporate personhood has a lot of other negative ramifications. Group entities should not be treated as individuals as they are because they essentially have all of the benefits of an individual, but none of the responsibilities. Each individual comprising a group entity can exercise their same rights without the group taking on the role of an specially protected individual.
