Jose Guerena was armed and a Marine vet protecting his family but Tuscon SWAT still killed him(1). But it can go the other way as police have been shot and killed in paramilitary raids. I brought up "stand your ground" laws as indicative of middle America's mindset for more lethal response to the perceived criminal threat in their communities. That mindset has also included support for harsher sentencing and more police, even as the "police industrial complex" grows more into a police state and military occupation.
"stand your ground" laws, are, I suppose, "more lethal" in the sense they don't require you to retreat if theoretically possible as viewed in the calm of a criminal trial, but I think you're otherwise vastly overstating what the "indicate". Using the loaded term "reactionary" strikes me as entirely out of place.
WRT to Jose Guerena, with the exception of Massachusetts at certain points in the '70s-80s, I don't know of any state that requires or required you to retreat from your own residence. It's unthinkable Arizona would have ever required that.
Finally, I don't see how it helps anything to paint people like us as racists, especially, as LyndsySimon points out, we've been the biggest group fighting for the longest time the tactics that are being discussed here.
