Being edged out of their own homes. In times past throughout the developing world, it was called colonialism by the natives, in Europe it’s labeled multiculturalism. Whole transplanting of peoples and cultures, from what could be accurately labeled, another planet, into the heart of Europe. Insanity and a moral outrage.
International law does not assign any priority to a nation’s citizens over any person who happens to stray across the border. At the ground level that means the end of borders and the end of citizenship, which is why immigration isn’t just a touchy issue in Arizona, it’s a touchy issue in Sydney, Tel Aviv and Birmingham. You can hardly open a newspaper of the liberal persuasion without being treated to another group of refugees in some troubled part of the world walled up behind fences and trying to get over to London, Sydney or New York.
This sort of thing can’t be called immigration anymore, it’s a straightforward migration and it has no apparent limits. However many you take in, there will be more waiting and always burdening you with an unsolvable crisis.
