Then why in God's name did you say that "real world scenarios range from drunken family members
to mentally ill people with assault rifles"? It is clear that you were implying a range with drunken family members being on the low-end of the violence spectrum.
See, that's my point, which you still seem to be missing. "Real self defense" is a lot more complicated than some random bozo in a bar, and so there is no one-size-fits-all answer.
