This ^^^. Is great logic and not dissimilar to some logic that I've been known to use with the wife...
And if she argues with her, just use the Alinsky style tactic of: "you're anti-science, aren't you!?" She'll be so caught off guard and not wanting to be thought of as anti-science, she'll beg you to buy the gun. Heck, that tactic gets Republicans in Congress to vote for Democrat bills, which of course, they never reciprocate the other way.
But, I digress...
