Brits, what's going on with people showing the England flag all of a sudden?

Heard people are using it to scare immigrants which is obviously awful. Saw 2 of them today during a walk which weren't there before... Seeing this hate against coloured people spreading around the world is NOT what I want to deal with or see. It's sick. Can we please just treat eachother with respect?? Just be kind, it's not hard...
