You seem to need it, Glade, so I'll explain that particular point more slowly.
I never at any time suggested VirginiaWildcat is an ACC fan. That he is an NU fan goes without saying. Literally, it is too obvious to bother mentioning. At the same time, he purportedly lives in Virginia, or did when he chose the moniker, or grew up there, or for whatever similar reason chose to tie his forum identity to that particular commonwealth.
Here's the tricky part, follow closely. By asking if he were confined by his physical location, in Virginia, to only following ACC football, I made the rhetorical point that we are none of us confined in the teams, conferences and coaches we pay attention to. Not by our physical location, not by our alma mater, and not by our favorite team. In fact, the point was that one can enjoy following teams and conferences from all around the nation, regardless of who they are. The serendipitous fact of his being an NU fan in ACC country absolutely made that point even more clear and potent, much better than if he'd been OhioWildcat or NorthwestEasternIllinoisWildcat.
In short, there are no walls in this "fan" business, unless you choose to erect them yourself. It is near-sighted, one might even say xenophobic, to suggest that we can or should only pay attention to our home team, or home region/conference.
That was the point, Glade. Hope this helps illuminate it for you.
