From what I see, the country is in denial about it. People are just not thinking about it. It might come up in conversation and people do a double-take, remembering "oh yeah, I forgot he's the Prime Minister now".
I was listening to a normie British Youtuber making a joke the other day about being secretly in with the establishment and he said "Boris Johnson and Liz Truss both told me". Rishi has been Prime Minister for months (and I had to think about that one) and the guy hasn't internalised it. I haven't either.
There are no funny Rishi memes like there were for Boris and Truss, really. Not in favour or against. Even the lefties are having a hard time getting their blood up about THE FUCKING TORIES!!!! at the moment because they know that this is what they wished for and even they're depressed about it now that it has happened. And they know they can't scream bloody murder about how evil the Prime Minister is SELLING OFF THE NHS!!!! because he's not white.
Nobody is talking about it, nobody is laughing about it. Nobody is even angry about it. The people who still dare to retain enough free thought to think a foreigner obviously shouldn't be PM, let alone this cunt, were already aware of how bad the situation is and not surprised by it when the globalists snuck the bastard in without even the formality of an election ahead of schedule.
It's such a heavy but totally banal blackpill that as a nation we've just simply not got around to acknowledging it.
