I do get what you are saying, and may offer some pov. I do not perceive anyone who breaks into my house as human, simply because I am aware of how weak I am. Not a gun owner, but if I am in kitchen, trust me I am grabbing a knife - anything to level the playing field - and setting myself on fight rather than flight.

But it’s mostly fear and adrenaline. If something happened, I have no doubt I would go for it to secure mine and my partner security. How much of a wreck I’d be later remains to be seen, though for sure it would hit me hard.

Honestly, not much difference between that and chihuahua. Fight to kill out of fear.
