I work in England in Education. I'm not English.
An Educational specialist came in our classroom this week and commented: "You have a lot of white blonde children here!" (random, not a statement followed by some statistical information or similar).
So, if that happened in my country, I would say, the person would sound as if it was part of some neo-Fascist or neo-Nazi group, or came directly from 100 years ago.
How about your country?
