I don't think anyone really thinks that exactly, Naomi. But superficially it's obvious that some people are far more concerned about the inconvenience to themselves than to others.
And besides, is it that outrageous a suggestion to make, really? Katie "Tells it like it is" Hopkins, whose pox-pops often get some level of support on here, came out once with some hope or suggestion that she wanted to see more "bodies [of Syrian refugees] floating in water". The first named victim of Grenfell was a Syrian refugee/migrant, as it happens. Is it really so outrageous and appalling a suggestion that KH, and those who like what she has to say, might have shed rather fewer tears when they learned who the victims were?
I agree it's a sensationalist way of expressing my views, but still: anyone moaning about potential loss of house value has a seriously warped sense of priorities and morals. I make no apology for phrasing it that way.
