> The President, within this context, identifies a single entity. As such, it is a proper noun

Yeah, no. You're just making things up to suit your position like the president does.

> no. You're just making things

...this isn't a counterargument. I can similarly assert you're justing making stuff up, which isn't untrue, either way, since we're talking about language, a wholly made-up enterprise.

What's your contention that the President, within the context of the American presidency, does not refer to a single entity? Is this a preference? Or something you actually believe is incorrect?
