The author isn't taking an individual quote and extrapolating to a group/ethos, he's observing a group/ethos and choosing a broadly representative quote therefrom.
"No, he's observing individuals from a group/ethnos and then extrapolating their quotes to the whole of the group/ethnos. You shall not extrapolate when dealing with people, you know."
Well hold on, the author is using contrasts as a stylistic choice, it's not exactly journalism, there are no journalistic standards to hold him up to, it's a blog post, he can write whatever he wants
I personally wouldn't police his style
> Well hold on,
No thank you. You said you liked the style and I said I don't.
