I also have yelled through the door, at another place I lived, as to the nature of a late-night visitor's knock on the door. I did that before opening the door.
To answer specifically: yes, I have found Utopia.
I do not want to be responsible for the death of someone's son. I lost a son via accident and a parent can never outlive the nightmare of it. I know I am unique but I would prefer to be shot dead by a minor child rather than to render the pain of his death upon a parent.
I do strongly support the right of self-defense and am well-equipped to defend myself, VERY RELUCTANTLY, if forced to- in a responsible and reasonable way.
....Stay Safe
