I don’t know. We clearly do follow political trends in the US. Throughout most of my life, the Democrats and Republicans represented different takes on the world, they had different worldviews, but they did not represent an insurmountable schism in the electorate - there was both some level of mutual respect, an acknowledgment of the need to at least try to govern on behalf of all, along with a respect for democracy itself.
I would say the same played out largely between Conservatives and Labour in the UK.
Trumpism effectively replaced Republicanism in the US - it is a personality cult that has been exploited as a means to achieve power and wealth, and it has ridden roughshod over ideas like civility and democratic norms whilst driving the US further to the right than at any point in living memory.
I think Farage is an eager student of Trumpism. We see a similar focus on crafting an “everyman” persona in spite of his wealth and background. We see the same focus on issues like immigration, including blatant use of racist tropes to provoke fear and anger. We see the lack of respect for the norms of behaviour that used to be expected of our politicians (never apologise, never appear to feel shame).
To the extent that Reform represents the UK’s first tentative steps down a path that is currently seeing innocent people murdered by armed, paramilitary style immigration enforcers on the streets of Minneapolis…I don’t think it is unreasonable to at least feel sick in your stomach (if not terrified) that where the US leads, the UK might follow.
