The protesters come from "shitholes," are "a violent & illegal mob," study "x-grievance programs in college," are "the enemy" and "deserve to be dropped." Cool cool, sorry to have engaged, I see that your mind is well made up.
Honestly it makes me sad and disappointed that you just casually talk about your fellow citizens or just fellow human beings like that. This isn't war, where sometimes you need to dehumanize and "other-ize" in order to kill the enemy; this is America.
What I'm arguing for re: this couple and your lionizing of them is that de-escalation of the situation and demonstrating responsible gun ownership would have been a better path.
These folks are not heroic for branshing loaded firearms at people on the street walking by their house, with fingers often on the triggers and while also occasionally barrel-checking each other's backs. That's reckless behavior that I know you wouldn't tolerate in a combat zone, let alone what should be the expectation while on your front lawn in Anytown, USA.
