This is a clear sign of the limit of the multiculturalist 'tollerant' approach which preaches open borders and acceptance of others. If one were to open the borders, the first to rebel would be the local working classes. It is thus becoming clear that the solution is not 'tear down the walls and let themin', the easy empty demand of soft-hearted liberal 'radicals'. The only true solution is to tear down the true wall, not the Immigration Department one, but the socio-economic one: to change society so that people will no longer desperately try to escape their own world.
