I have been where you are and you have tunnel vision. The day will come,believe you me. That is if you live long enough.
1. Trying to figure out if that's a threat-- FAIL
2. Subroutine: if it is a threat, is the person making it more or less likely to be carrying what I'm carrying -- LESS
3. Trying to determine whether, if it's a threat, whether I should care or not -- NOT
4. Conclusion: At 44, having faced death for my country from a foreign enemy at 26, I sense that there may be a domestic enemy at my heels; but since that individual is likely to be armed with only with words and little wit, I choose to ignore its petulant whinging and get on with life.
Farewell.
