When you say some revolution that will/may come, is it an arm revolution that you are talking about?
If yes, then there may be a real reason why some people need to pile up the firearms.
There are revolutions in the field of technology, biological sciences, chemistry, thoughts…..but in any society there will be always a small sector who dream about armed revolution. It’s a means for them to gain power with the power of the gun instead of using some grey matter.
Even when we want changes, we have better ways to push for change in our institutions rather than “revolution”.
Anyway, I don’t trust the guy down the street with revolutionary guns. I must say that I trust our government 100 times more.
