re: Why are they being denied access to Europe?

‘What if they were to come? I did not know who "they" were, but it seemed inevitable to me that the numberless disinherited people of the South would, like a tidal wave, set sail one day for this opulent shore, our fortunate country's wide-gaping frontier.’

Jean Raspail’s question is being answered. I think what you are seeing in Italy with African migrants and in the US with South/Central American and Mexican migrants is just the start. In 10 years Europe will be unrecognizable and they’ll realize their demographic suicide began years ago.
