Well, for one, I am not in the UK, I just listen to a lot of UK podcasts and have friends from there, and two, the majority of the right-wing social media out there is already grift, mostly from the UK, but also a substantial portion is from people in South-East Asian and India who barely understand English politics but understand that racism gets clicks. It's literally just people following the algorithm and capitalizing on the aggrievement market.
It's not just any old schmuck though, TR has a long history within the far right in England, however you can very easily make up and capitalize on the racist narratives, if you wanted to do that.
So, like, get on it, king. Ride that Zuckerberg and Musk money.
