The majority of the US is absolutely not like this.
You keep accusing other people of living in a bubble, but you're indexing your entire experience on to anecdotes of where you grew up as an individual experience.
In all honesty, statistically, that person's assertions are highly likely not to be fact.
It's like the man who has happened on "several" three-alarm fires in his life. How many times does a person happen on even one three-alarm fire in a lifetime? Let alone "several". The likelihood you're either speaking to an arsonist or a liar is very high.
Same is true for people who are robbed at gunpoint "several" times. The statistical likelihood that you're either speaking to a criminal or a liar is extremely high.
Hmm. I don't know the race of the poster you are referring to. I do know from friends who were not White, their experience living in the South was vastly different from mine.
