Serious question: Why are so many people "going postal" in the US as of recently? "

1. A permission structure that mimics the fat slob who is cosplaying being president with his credo: "I hate my opponents. I don't wish them well."

2. An economy that is being presented as "hot," but is shedding jobs with limited opportunities, and growing dissatisfaction with day-to-day living.

3. An authoritarian rigor that is encouraging the classic human revolt against authority figures.

4. A craving for social media attention.

5. Burnout from all the above.
