I have seen this before,, Living down South it's not uncommon to encounter Crazy Old Guys with extreme values. An the early stages of some Dementia are showing signs of extreme anger for sure.
What's the odds of you encountering this Goof Ball again,, Me I would have had some fun with him, But that's just me and my Twisted Brain. Better not come up or out spewing your redneck wanna be beliefs on me,, I was the original Red Neck,, Easy,, Very Easy thing to be or portray ,, Just close your mind and don't Agree with anything unless EVERYONE else agree's . See how simple it is?
Trust this and Believe what I am telling you from a Vet, There is NOTHING those Clowns have or will ever do that this Clown hasn't done, So why fear them ????
Ohhhhhhhhh I don't ,, Maybe a MMA fighter that's it,, An I could give him a run too,, So pick and chose your battles,, Some are lost causes !
