The US Supreme Court is the final arbiter of the US Constitution as it stands at any given time.
As social and political personhood is reserved for the natural human entity to be exercised during his/her brief, spiritual, variable capacity lifetime, with 'artificial collectives' (secular or otherwise) playing a supportive role, the above inventive 5-4 judicial ruling leads to alienation of human beings; a setback for current human existence and its potential.
Was personhood meant for human creations such as 'corporations' that are designed in haste and have evolved over a few centuries to have continual rejuvenation and the provision for perpetual existence?
The ruling dilutes the comprehensive political assignment granted with protections to the person by the US Constitution to formulate and guide the future of local human society (in the global village), as it enables competition and incursion by 'non-human' corporations over human futures.
And since money is required for practical politics of which a person could have but little while corporations have much at any given time, the ruling corrupts the political process through identity theft.
