My take on English attitude towards this type of situation is 'all nice if on top but get weird if not'.
I would not try to make Englishness a virtue which 'explains' things.

Remember, this is the island of binge drinking brexit idiots, lets get some perspective on the over-hyped and mythical British 'correctness'. This was never a thing really. It was cultivated though, creating myths is a quality they have and gladly believe.
