That is certainly a view shared by quite a few, varian. Cameron's handling of the his own party euro-sceptic agitators, of calling the referendum when he did and then of copping out of finishing the job when the vote went to Brexit (though I can also understand his saying that he is not the right man to do it) do make it look as though it could have been better 'stage managed'. But who knows, and anyway it's done. Now we're at the point where politicians should get down to work and sort things out while the rest of us yabber on and, in effect, wait and see what the fall out is.
Re racist attacks, yes they are as shocking as they always are, and as pointless.
