That's like saying the remain vote was influenced by the fear of the promised 'emergency budget' etc etc. Of course immigration is weaponised by some fruitcakes when they have nothing else to offer - the last few days on this thread being a case in point. The whole debate on immigration has been reduced to a polarised slanging match by two equally thoughtless sets of loons. It's the equivalent of arguing how best to drive a car based on two options - leave it in the garage or drive at 100mph all the time and nothing in-between. We need immigration, but we also need to monitor and control it. Not only do we need to keep out the people who blow themselves up at pop concerts, but also the gangsters that invest a couple of million in Cypriot property, get a shiny purple passport for their trouble and arrive in London in a sharp suit on a private jet. At the same time we need to let in the people we need, and also have the humanity to provide refuge to those in need, and even allow for some decent folk who would just like to live here.
Wether it's a RW anti-immigrant loon, or an open door policy loon, both damage and polarise the debate to the detriment of all. To constantly drag brexit down into this sort of ideological gutter does intelligent discussion (or immigrants) no favours and is every bit as bad as what Farage and Yaxley Lennon do.
