I really feel bad for all non anglo people living in England. I have seen quite a few articles about how England has always had xenophobia against immigrants for decades and it has continued to rise since the last recession to the point of voting for this Brexit disaster. It does not matter if you are Polish or Muslim, these nationalist hate you for not being Anglo-Saxon. Saying Keep Britain British means you basically want to keep Britain anglo-saxon which is extremely racist. As someone from Jewish and Eastern European descent the US government pulled this bullshit on people in my family nearly hundred years ago. The government said that Eastern Europeans were substandard compared to Anglo Saxon descent people.
I feel like I am living in the 1920's and 1930's again with all this rise of rightwing nationalism which is scary. Hopefully the Brexit backfires so rightwing nationalism can be finally killed off.
