Even more ridiculous than the idea that a fertilized human egg is a human being, is that large, amorphous agglomerations of people can form a person. A company, a corporation, an interest group... that these clusters of people, brought together by similarity of thought or by economic necessity, are artificial creations, a form of human breccia, which cannot be construed as having a homogeneous mind and singular being. They are aggregated together from disparate portions of society, and are entities whose existence is totally dependent on human law for definition. They did not arise spontaneously from a primordial ooze, nor were they birthed by some titanic polyglot mother.
This is an important distinction, in that such groups of people in their various forms, believe that somehow their mere existence provides them the same access to rights and privileges that a natural-born person enjoys, namely in the area of freedom of speech, and under that, the ability to influence elections based on their desire for certain outcomes. The absurdity of this notion is lost upon corporate boards and self-important leaders, alike; their belief in the rightness of their cause or business is such that it blinds them to fact.
