Are you able to substantiate any of that ? It comes across as a bit of a superiority complex about your social group and where you live. Not a good look to casually insult people although the ‘5 years’ bit is probably the giveaway (referendum reference by any chance ?). This thread has descended into the same old name calling and hopefully is headed to the bear pit.
He's right though, isn't he? Those with bigoted views do seem to have been emboldened in recent years (see organisations such as Britain First and the EDL) - perhaps this notion is amplified as the internet has connected us more to those outside our social bubble. Like it or not, the unpleasantness of 2016 added to it.
