This 30% of Americans can best be described as martyrs. They’re not wearing suicide vests, to be sure — although every now and then one of them shoots up a church, school, office. But they are martyrs nonetheless — people who are happier dying for a cause than living for one.
Not sure how I feel about promoting hyper-polarized tribalism. Seems counterintuitive to divide America further and to alienate 30% of the population. Also describing 30% of Americans as extremists predisposed to become shooters, even if it is just cited as a placeholder for the sake of the article, seems misleading.
