It’s all in the tone.
The tone of the voice; the demeanour; the ‘conversation’.
Whilst this is a possible ‘playing to the audience’ dialogue, it is symptomatic of a superiority mentality, played out in every day events between those who believe they are superior to those they dub to be, inferior.
What is particularly telling of this ethnocentric bullshit, is that ‘they’ believe they hold the moral high ground, which is the classic savage versus civilised mentality. That because they are ‘better’ than the ‘others’, their opinions, whether based on fact or not, are indeed, right.
