Creative Speculation

Internal strength eviscerated, taught to worship narcissistic leaders to the point of moral and financial bankruptcy, anger directed against demonized political opponents, guns as a solution to anger and insecurity, stir the rage daily with a talk show home fryer, and you have loose cannons ready to blaze on any given day.

The trauma bond is they're being flattered, protected, energized at the same time they're being used, exploited, denigrated, disrespected. They lose their minds to demi-gods hell bent on power and money. I wonder if these shooters feel on a gut level that they are only trying to do their part in the power grab.
