Disc brake advice please

Well, I guess there are two schools of thought on that;
1) is;if they are left-hand threads then well you know, it is very easy to snap them with an air gun set on stun.......for loosening right hand threads.and
2) is well that's what they make torque wrenches for.

Maybe I'm just lucky. But I have jumped my car, slammed it into curbs hard enough to break aluminum wheels, and slammed them into potholes at 60mph that nearly shook my fillings out! Yet there they are......saying,"is that all you got"?
