No offense, but when I hear someone talk about being a “warrior” I picture the kind of guys who can’t help reminding you how lethal they are. It gets old fast.
I think taking responsibility for your family’s safety is admirable. But as other folks have noted, there are many threats other than physical violence that would be irresponsible to ignore. Every hour, every dollar spent training for combat has an opportunity cost. Is the extra hour at the gym better for your family than an hour spent reading with your kids? What happens if you get hurt when you’re training/playing? Is it really for the family, or is it all about you?
It’s hard figuring out how to allocate your resources. How do you balance preparing for something highly unlikely but potentially devastating against things that are less severe but more likely? How much is enough? It’s good to be prepared to defend your home against intruders, but if you’ve got a pallet of ammo and crappy smoke detectors you might want to rethink your priorities.
And if you truly think that violent attack is the most likely threat to your family, you might want to expend resources in moving somewhere safer.
On a more practical note, there are some concrete ideas here:
