I wouldn't say ALL white men own guns due to a fear of black folk, but obviously that IS a/the reason many do, and why many carry, and fear of black folk IS what stand your ground laws are all about. And obviously many of our corporate state police are too afraid of black folk to do their jobs properly. And obviously the NRA has routinely baited and promoted this fear in many whites. But hey, the fear, which comes ultimately from guilt, is part of the fabric of american society. All a direct lingering result of the nation's founding and slavery.
