The rules of conduct here are what you would expect in any civilized home: be civil to others, don't advocate commission of capital crimes and keep the language and the imagery tame.

Very well. I read my dictionary, Mr. Brady, and here are a couple of definitions I found online as well.
Escalate: to increase in extent, volume, number, amount, intensity, or scope
To increase, enlarge, or intensify
The screaming racist bum aside, pulling a gun on someone who is actually threatening or using force against you may very well de-escalate the "encounter" if it causes the bad actor to run away, shut up, or take a well-deserved bullet (if things become that serious). The mere presence of a gun doesn't necessarily escalate anything, and may often prevent violence. By your own faulty definiton of "escalate," you're still wrong if the other party has a weapon of comparable or greater lethality.
