Wow, just wow… This is exactly how I feel (not a black man), but situations are a bit different. After being in the USAF for ten years (deployed for almost half of that), I honestly believe and use “I’m color blind”
Mind you, like any other human I have my ticks and triggers. My biggest are supremacists, after being in trenches with evey skin color imaginable, fighting yet another…. Anyhow, I agree with your uncle, I too didn’t verbally say the pledge but for another reason…. And like you, I’m a self proclaimed asshole!
