I'm absolutely appalled at how many of you think that fence comment was bad. A fence or wall that's able to keep people out, assuming that such a thing could -- much less should -- be built, could also be used to keep us in. Not that it's a guarantee that it would be used in such a manner, but it could be. That's so obvious that I can't believe anyone could disagree with it, and anyone who would is so dumb and naive that it wouldn't be worth the effort to explain it to them further.
I guess I can see their perspective, though: no one in government ever lies about the real purpose of any government action beforehand, and government as an institution certainly has no record of physically restraining people within its arbitrary borders, or in prisons or concentration camps. That's all just nutty conspiracy stuff.
