You can moan all you like, but you have to accept that a significant proportion of the population feel as she does. I’m not saying I agree with it - far from it - but like it or not, she speaks for many.
Personally I think immigration has been very badly managed, and freedom of movement should have come with more controls early on. It seems to me that, apart from a small minority of nasty racists, we all coexisted fairly harmoniously for a few decades. It’s the opening of the gates to huge numbers of Eastern Europeans that seems to have been the trigger for a resurgence in racism. This combined with relentless public spending cuts has brought out the worst in people.
Humans are tribal by nature, and whilst a degree of integration of perceived “outsiders” is acceptable to most, there is a tipping point at which a larger number of people get annoyed and defensive. I think governments have taken us past that tipping point, and now racist views are seen as acceptable and (in some areas) mainstream.
I’m not saying I agree with any of it, but I think there are anthropological and psychological explanations for the nastiness we are seeing now. And it could have been prevented by better politicians.
