That flag is being cynically used to blind a lot of people to the sheer lack of talent and incompetence currently sitting round the cabinet table. The inference is if you criticise chancers like Buckland, Williamson, Patel, Raab, Fox, Matt Vickers, Simon Clarke et al then you are somehow criticising the country. Its there to make people think twice about asking difficult questions ("do I really need the hassle from the faux-patriots today?") and its an easy way to keep the flag-shaggers distracted and foaming at the mouth at the 'lefties' 'wokes' 'media scum'.
It's Brexit nationalism and the bullying tactics that got us to this point being rammed down the throats of at least 48% of the population, and its going to go on until the next election so steel yourself for the long haul - because its going to get more suffocating before it gets better. It worked for Trump and his cronies during his four years in office - all sorts of crimes and despicable behaviour hidden behind the stars and stripes.
By the way it can't have escaped notice that Naga is the one being targeted (for basically laughing) by the usual suspects while Charlie Stayt is not even mentioned.
