The right-left spectrum is just a construct, a made up thing that doesn't have much bearing on reality.

In reality politics is about pressure, not ideology. The the Democrats had the Whitehouse and Congress for a few decades, the US would be what you'd consider to be "further left" than Europe. Demcoracy is a process not a checkout on Amazon. You don't choose which ideology suits you best (ideology is all just a scam) you choose which direction you want to pressure the government to go in.

Right now in Europe the pressure is going rightwards.

Fascism is a funny thing because it's a hard focus on emotional manipulation to make it acceptable to flip the board and have a group of people seize authoritarian power. Communism is similar, they just exploit different emotional pressure points. A right-left distinction between radical ideologies is really silly since they're all ultimately about emotionally manipulating people into being angry enough to think authoritarianism is a good thing. One promises to make you stronger another promises you make you more equal, but in the end it's just authoritarianism.

Obviously the US is currently more vulnerable to this than Europe at the moment, but let's not get under the illusion that Europe is safe because of made up political spectrums when so many people have been brainwashed by ideological bullshit in both places. Same goes for Canada (where I'm from) at the moment as much as it pains me to admit it.

I'd say the UK would be safer than both Continental Europe or Canada at the moment, since it's guaranteed there will be at least four years without there being a chance of things going fascist, and it seems people there have generally gotten tired of the ideological bullshit and just want political stability. I doubt Kier Starmer will be doing any ideological purges.
