The extremism is from one side, but there is a risk that, to protect against that extremism, a polar opposite comes (Liberals most probably). Also, maybe im misunserstanding the word “polarisation”, but i understand it to mean “two polar opposites”, neither of which is necessarily extremist. For instance, I would argue that the US is polarised, but only the Republicans are the extremists, while Democrats are a defensive response to the Republicans.
