@Nutmuncher- I've had some time to think about the polarisation question we've been discussing.
I guess my view on the UK being more polarised than the US is based on the following:
-I read more national newspapers at home than I do in the US
-I listen to Radio 4 and The Times radio heavily
-Most of the social media people I follow or podcasts I listen to are UK based
However, I very rarely discuss politics with my family/friends and never with colleagues.
Meanwhile, when I go to the US, (Austin, Texas and the SF Bay Area - both strong democratic areas) I'm not exposed to the same level of media, formal or social. The TV news channels and radio stations tend to be locally focused and the newspapers we get in the office are local, metropolitan ones too.
My colleagues, who are predominantly (legal) immigrant Indians, don't discuss politics (not woth me anyway) and I've no idea of their affiliations (I can hazard a good guess)
I guess what I'm saying is my view that the UK is as strongly polarised, politically, or possibly more so than the USA; is based on the increased exposure I have to political viewpoints,via various media formats, in the UK compared to the USA.
I guess what this ramble should conclude with is that I have a bias based on being more (not necessarily better) informed about the UK political scene.
P.S. I actually live in Northern Ireland - dont get me started on the political situation here 😀
