You are spouting some utter nonsense there. Many people on the Leave side are clearly concerned about more than immigration. Also, concerns over immigration do not make people Little Englanders. Voting to leave does not mean that you are voting for no immigration, anyone that thinks that is under a false illusion: immigration will continue but the rules on how you get to migrate to the UK will change. If we leave the EU, we will continue to welcome immigrants from all over the world, including from across the EU.
