I think it's extremely naive and inaccurate to suggest that Britain has just become racist in the last few days, or that people are only experiencing racism/xenophobia now.
Britain has been racist and xenophobic for a long time. And people have suffered racist abuse for a long time.
My dad was English. My mum was white, but from another European country.
They used to live in England together.
My mum told me that every week she was sneered and laughed at for not being English. She was told to "fuck off home" about once or twice a month . She was talked down to and made to feel like a second class citizen all the time
She said the last straw was this : my brother was in primary school and he had got something like a low mark on a test. My mother was talking to the English teacher at parent teachers meeting, and they spoke about the test.
The teacher said about my brother failing the test to my mother :
"sure what do you expect, he's half Polish" and laughed.
(not the country my mums from but I'm using ithe country as an example. And the teacher laughed into my mother's face After that
My mother told me she couldn't take the abuse and nastiness anymore, that was the last straw. and she left England and went back to her home country.
This broke up the marriage between my parents as well. Racism and xenophobia broke up my parents marriage.
It's very stupid to be racist and xenophobic when a lot of English people are married to non English people.
