The first point of your comment I completely disagree with; the second point acknowledges why the the first point is bullshit to begin with. Yes, someone can be incompetent and require corrective action. This was not it and completely, grossly unacceptable. That he had to adjust his behavior is an acknowledgement to this. We are all flawed humans; but some are more flawed than others. That being said, if it’s true he has reflected and taken corrective action on his own negative behaviors, kudos to him.
Dad (a mountain Appalachian man who did own guns but always hated gun nut culture) always said it was better to use your brain than bullets. I wholly agree with your assessment that if we’re at the point where we need guns, then we’ve already lost.
