Serious How is being told you forgot your manners a harsh criticism

I watched the adorable Jazz owner give her great speech in which she said the so-called fan "forgot his manners". To me that sounds like understatement of the year, and far from a harsh criticism. Especially when the guy had a clear history of bigotry. When I raised this on the speech thread I was told if I had been on the Earth for more than 10 years and wasnt retarded I would know this was as heavy as could be in Utah, and that I was mocking the local dialect. I genuinely would like to know how this is a harsh reprimand, because my friends dont get it either, and I am siding with my black buddy who was furious about this.
