Apprehensive about being English in Scotland? There's very little anti-English rhetoric in Scotland at the moment. I've lived here 40 years, it's virtually a murmur compared to how it used to be. The battle lines are drawn along different divisions at the moment.
There is a fanaticism in the air, it's a very strange time.
Yes, I can see politics being pushed to the extreme in at least two directions! But I am not sure how much of it is idealism/ideology driven and how much neo-liberal manipulation. People like Cummings don't strike me as ideologues - just people who can see how useful divisive ideas can be as tools for manipulation. I think 'wokeness' is one of those - as was Brexit, Scottish independence, etc. Destabilising, polarising, emotive subjects. In the US, that issue seems to be race. The Russian interference is another matter - these 'wedge' issues. Used to divert, but with unfortunately potentially serious consequences for everyday life. And sometimes handy vehicles for justifying restricting civil liberties.
