My initial point is that Americans are still armed. No one has taken their guns away. Australians are defenseless in that respect.
Keep in mind even a docile rabbit when corned will finally bite and attack you to defend itself.
Americans can only be pushed so far.. as witnessed by the historical Civil War which caught this Country by surprise during that era of the 19th century.
Americans can be only pushed so far you say. Just how far do they have to be pushed? Will they rise to the occasion when they are blocked from going to the grocery store? How far? What do the tyrannists have to do to raise some ire in these fearsome armed super-bloggers?
