Fair enough. But while it might make sense to distinguish between corporations and individuals in some contexts, it seems to me an inapt distinction to make in this context. And if we think through what we're talking about when we talk about corporations, I think we (in most contexts) come to the nearly inescapable conclusion that what we're really talking about being implicated are the rights of individuals rather than the supposed rights of corporations. But we've probably discussed that general issue before and likely will again, so I guess we don't need to get lost in it right now.
That said, did David and vrai not organize as a corporation for the purposes of owning and running this site? That would surprise me (if would surprise me greatly if they weren't at least organized as an LLC, which technically may not be a corporation but the some of the same issues - and the same basic notion - would still be in play). Perhaps you would further distinguish closely held corporations from not closely held ones. But again, while that distinction might be relevant in some contexts, it isn't clear to me why it would be relevant to a significant degree in the context of property rights. The notion of owning property - which may only be a societal construct, but represents an important, I'd say essential, foundation of societal organization itself - necessarily carries with it the right to make a wide range of decisions with regard to the use of the property that is owned (or otherwise legitimately controlled, e.g. by proxy or license).
What else do you think corporations that serve the public should not have say in when it comes to the premises (or operations) they own? Can they, e.g., require that you be polite to other customers beyond the degree to which the government could? Can they prohibit certain kinds of expression, or only to the degree the government could? Can they favor particular content or viewpoints? Do they have to allow all activities on their premises which the government itself would not have the authority to prohibit? Your position seems incredibly problematic to more in addition to just being wrong in principle based on the general notion of liberty on which so much of this nation's rules, as well as its culture, was built.
