I have nothing against immigration, so long as it's done legally. I have nothing against illegal immigrants either and often feel there should be pathways to citizenship so long as the illegal immigrant commits no wrongdoings and contributes to the success of the economy of the place they are staying in. The problem with Calais in France is that quite often, terrorists disguised as immigrants make their way in through this area and then commit acts of terror which harm French citizens. French people want to help those that have been displaced in the Middle East, but Calais is a mess.
