Going back to the op, a bullet point overview on Pershing that ends with a short narrative including undocumented events with specific allegations, ironically involving Muslims and execution before WWI. In some circles this added information may raise the bar, more likely this is something that started out on a much smaller event, that has been embellished and exaggerated over time. I wasn't present when this was going down, my spin on it, a trooper shot a hostile the bullet past through them striking a pig and the story grows out of this bs.
Maybe a better question is, why does America hate me, a working class citizen?
