The whole episode is part of the Right's 'culture war' - create an outrage or imaginary threat (Last Night of the Proms under attack, BLM a Marxist front, Christmas being banned to avoid offending the effnix, 'Ba Ba Black Sheep' banned for being racist, etc), and then use it to attack 'leftists' and 'liberals', while moaning "It's PC gone mad; you can't say anything anymore without 'snowflakes' getting offended and having you sacked from your job."
These entirely manufactured outrages are integral to the Right's tactic of diverting public attention and (potential) anger away from the real problems - poverty wages while CEOs pay themselves £millions, food banks (in the world's 6th richest country), homelessness and unaffordable housing, the constant selling-off of our industries and companies to foreign firms and governments (the opposite of "taking back control"), the privatisation-by-stealth of the NHS and other public services (often sold to Tory donors), some of the lowest old age pensions in Europe, and the appalling treatment of the elderly in many of our so-called care homes.
But that's the whole point of the Right's pretended fury over Last Night of the Proms, migrants in dinghies in the English Channel, BLM, 'cancel culture' - it diverts public attention and anger towards 'fake' targets, and channels public outrage against 'liberals' and 'the political correctness brigade', thus allowing the top 1% to continue getting even richer and avoiding paying taxes while millions of ordinary working people struggle to feed themselves or pay their rent. Ensures that 'the people' don't turn their anger against the Tories and the Establishment.
Sadly - as a lot of posters and angry comments on here illustrate - this tactic works; people keep falling for it.
Always love how some people think there is this such definite line down the middle with 'lefties' on the left of it and 'righties' on the right. Such a black and white view when life is really much more a shade of grey.
