Weirdly most people don't support attacking police and bricking mosques. IF you believe there’s this revolutionary undercurrent in the UK that thinks riots are OK, you're like Faragesque radicalised Muskite, and living in a fantasy.
If you bother to look at the Yougov polling, a lot of people were sympathetic to the peaceful protest on immigration, 35% had a fair amount of sympathy and 23% a lot of sympathy, that's nearly 60%.
That sounds about right, most people have immigration concerns, that doesn't translate to fucking dragging out non white English people from cars and burning police stations!
