It is tempting not to bother about the media spat about Eurovision entrant Olly Alexander. Both Eurovision and Olly Alexander are deeply trivial, and Eurovision hasn't been fun for a long time. However, this spat - he called the British flag "divisive" - raises many significant issues, as it was intended to, although you have to look past the immediate to see them.
Most immediately, though, it doesn't take much to notice that Olly Alexander is himself being deliberately divisive. His whole transgressive persona is a deliberate provocation, designed to upset and alienate regular people. He is not even pretending to be representative of them. This is entirely to be expected. Eurovision entrants stopped pretending they actually represent anyone years ago. Eurovision has been a life-sapping insult to popular music for decades, and it doesn't take much to see it as sort of a repellent EU Frankenstein, degrading culture and dissolving boundaries in an ever-closer globalism.
Beyond this shadow play, however, are significant issues that will not be resolved in Eurovision. That is, what the symbols of the UK do and should represent; whose interests and culture those symbols should represent; who has the legitimate right to say what those interests are; and all the many related issues. These are all issues that are at the heart of the most intractable conflicts in the UK, Britain, and the constituent nations. This is not a coincidence, and it should not be surprising. That is why going back to some Last Night of the Proms flag-waving would not fix this. The globalist project to dissolve all nations has been very advanced for a long time, and the British establishment have been enthusiastic globalists for as long as anyone can remember.
And, actually, yes, the British flag should be divisive; this is a good thing and it is currently not divisive enough. It should divide the British from Olly Alexander and whoever created him. For better or worse, symbols like the flag represent a real population of perfectly good people, and their natural and legitimate interests. The gyrations of Olly Alexander and the like are designed to waft decay under their noses, cultural and political, and to mock them with it, saying It's Only A Bit of Fun. We deserve better than that, and we should let them know it.
