I'll have a look at Bob Vylan but if you have any clear quotes if him making anti - Jewish statements, then please send them. Nobody should be celebrating someone shot in front of his children...full stop, though it is disheartening that so many seem more saddened by Kirk's death than the deliberate starvation imposed on thousands of children in Gaza.
Anyway, these points are somewhat secondary to your point on immigration. I personally feel that we will not stop the levels of immigration we have seen, and nor should we waste our time doing so and allowing it to takeover all political debate for the benefit of a single party. I want the ability to live and work anywhere, so I would be a hypocrite if I wanted to stop immigration here. Housebuilding and public services need massive investment and suffered, badly, under the austerity measures imposed by successive governments. There is an estimated 21 trillion of offshore wealth, added into companies like Amazon routing profits through Luxembourg to avoid tax. That is where I would begin to generate the funds needed to develop proper public services for a rising population.
