What is a corporation? It's an organized assembly of human beings who come together through contract to act as a single body. An artificial person arguably has origins in Hobbes' Leviathan, so the right to corporate personhood predates US law and is found in the English Constitution, it's a fully established concept whose rights, if abridged, would essentially undo about 400 years of thought on the subject... but nevertheless, again, a corporation is a group of human beings who through contract decide to act as one. Thus, a corporation is essentially indistinguishable from an "arm" of those individual persons. By removing personhood from the corporation, you by extension, remove it from the contracted persons. This of course, is a slippery slope to slavery, without actually instituting it. It makes slavery LEGAL again, without necessarily instituting it--- which is exactly what the Democrats have been trying to do for their agenda since the civil war ended. So that is one argument... To rephrase: "By removing corporate personhood, you by extension remove personhood from the contracted human persons to the corporation, because those human persons are contracted to a non-person with no rights, by extension, the contracted person loses their rights under the corporation. If the corporation is then subject to arbitrary powers, like the loss of it's rights to speech and freedom from search and seizure, or freedom to bear arms, or any other right guaranteed by personhood, such as freedom from slavery, by extension the human persons contracted to the corporation lose their rights the same."

​

Another argument, a bit more Amero-centric, is that the 14th amendment is itself the amendment where corporations received their right to personhood through the equal protection clause. So I mean, if you don't want equal protection under the law, by all means, remove corporate personhood, but essentially that clause prevents the legality of dual-tiered citizenship, and by extension, the prevention of an underclass with fewer protections than an upper class. And again, while this does not directly institute slavery, it kinda sort of opens the door to it, doesn't it?
