I just want to add that I think we do have common interests, I really do. I'm being quite argumentative on this thread because I passionately think that we need a course-correction on immigration to AVOID even further backlash, violence, imprisonment etc. Against immigrants and others who get caught up in it. I think we both don't want that.
To the extent that violence has been able to be controlled it's because enough people still believe that there is a path through the legal system, rule of law, parliament etc which will reduce immigration total numbers and improve immigration "quality" (skilled, law-abiding, integrating, etc).
The last 5 years have been an extreme step change in the negative. Any immigration chart will show you this immediately. This has directly led to the negative sentiment we see on the streets today. Directly. It is a consequence of what people see with their eyes.
There is still a chance to go through the legal system to fix this, by significantly raising the bar for ILR, letting many visas expire naturally, and enforcing people to leave the country when that happens. That chance is slipping away though.
I think, strongly, that arguments about how we are just stuck with it and there is no going back, everyone here currently will be here forever with ever-ratcheting access to state support - I think comments like that are what turn people to look outside the legal system, and to violence, and to rioting.
