I wouldn’t be surprised if my town was the exception and not the norm (I’m from a relatively progressive town in a consistently blue state) but at my public high school I only knew of 1-2 people out of the 500 people in my grade that stood up during the pledge of allegiance and a good percentage of the grade hated them because they were high key homophobic.
Not sure about rural towns but I’m pretty sure this is the case in most cities/big towns in the US as well. It’s just that police training in the US tends to systemically filter decent human beings out of its system. Not exactly random, more like maximally bad by design 🙃
