Does Scarlette need a gun?

This is Scarlette.
In light of your limited knowledge of Scarlette, does she need a gun?
If she had one, would you try to take it from her?
You might feel insufficiently informed to make that decision or take that action, but if you favour gun control, then you've already answered, 'No, she doesn't', and should have said, 'Yes, I would'.
She is familiar with her circumstances and capabilities, while you are not; so when you boldly declare that she should be disarmed, you're claiming that your wisdom and insight on the world in general, filtered through zero knowledge of Scarlette, is superior to her wisdom and insight on the world in general viewed through her intimate knowledge of her personal circumstances. It isn't.
Its easy to ask the police to impose your values on a large group; but far more confronting to personally, directly threaten to attack a complete stranger, about whom you know nothing, for having a thing you don't like.
The former is the latter, with all of the arrogance but none of the bravery.
