I agree. Reform voters are fixated on immigration, but what they really mean is that Britain should be a white country. They often talk about "indigenous" people being pushed out and say that it was better in the UK before WW2, but they don't seem to understand that Britain had an empire that included India, much of Caribbean, much of Africa, etc. (I'll leave out the Romans, Norman, Huguenots, et al) and that people living in those subject nations had the right to come here. Many of those hated brown and black people also fought for the allies in WW2. Many people came in the 1950s and 1960s were recruited to do jobs that the "indigenous" people didn't want to do, and they were treated with hostility.
The hostility we see today is not just towards asylum seekers, but is often directed at public sector workers, including doctors, nurses, and other hospital staff, GPs, and teachers, who are leaving in droves, and then they complain about waiting lists and delays in A&E, and blame that on the Labour government. It's frankly batshit crazy, and I am ashamed to be British these days, something I never thought that I'd feel until Brexit happened.
