"Do you have what it takes?" is a very serious question. Personally, even at 56, I am physically and mentally able to handle whatever I need to, as the situation arises. However...
The more pertinent issue, to me, anyway, is whether we are prepared to leave family and hearth if we need to. Think about this, especially you brothers with jobs, young kids. Are you prepared to leave all that to fight the good fight? How would your family survive? Could you really kiss the wife and kids goodbye? Even those of us, like me, who are older and whose kids are grown are really gonna struggle with this. It's easy to be a "keyboard warrior", it's not easy at all to put it on the line, like the Founders did, many of whom died alone and penniless.
This all is different than handling a life/death situation which presents itself suddenly and which you must deal with.
Here's the $64,000 question in my mind: Suppose we hear of another New Orleans where "they" are going door to door disarming the populace. What are we going to do? Wait for "them" to arrive in our town and go out individually? Converge "en mass" on the town in question to stand with our fellow Americans? Stand with the "militia" in our locale? Do you even have a "militia" in your town? I don't.
Tough, tough questions...let's not kid ourselves.
