First, you didn't preface your original comment with any such "ifs." You made a blanket statement that implied applicability to all circumstances.
Umm... no I was pretty clear with my prefaces.
This is true. But you've also escalated a situation needlessly (IMO). However, as you pointed out, this could be different if you were infirm and continued blows would be deadly and leaving the area could not be accomplished quickly.
I'm not saying pulling a gun is a terrible idea, just that I think there are better alternatives for most people.
It's rather caddish to say that everyone must live their lives on your terms though.
When was this ever said or even implied?
I stand by my assessment of the OP situation that for most people, the presence of the gun was unnecessary. You might not be one of those people-- and that's OK.
