The British are generally very polite,
Of course, without denial, that`s British culture. But only on the surface. Open display of hatred or simple resentment is considered vulgar by Brits who try to copy the manners of their cultured royals and aristocrats. Let`s not forget that the main reason for successful Brexit was the massive influx of immigrants, mainly from Poland. Brits had enough and I can easily understand them, coz, with a tongue in my cheek, I already expressed my delight at a lot of Polish useless pathological scum moving to Britain after the borders were open.
