I don't buy any of that. Where to begin? First, "white" is not a deep historical identity. "Whiteness" was constructed in the 19th century as an excuse to persecute "non-whites."
Second: The "immigrant crisis" hysteria about alleged brown-skinned criminal hordes overrunning Europe is RACIST BULLSHIT. Hundreds of millions of dollars in propaganda money has produced this bogus perception of a crisis, which is fed by hysterical lies — exactly like the hysterical lies about black rapists in America circa the 1920s that led to the lynching epidemic. Sure, rapes sometimes happen. But mass hysteria also happens. Here is a recent story that sums up the entire situation: Mass sexual assaults by refugees in Frankfurt ‘completely made up’. These are just two who got caught, out of the hundreds or thousands of hysterical liars and second-hand-rumor-mongers who get away with it. It's exactly like the "lynching" stories of old. People spreading this hysteria are committing one of the worst crimes against humanity, propaganda for genocide. (Many are presumably getting paid by the Islamophobia industry to do so.)
Third: To the extent that impoverished immigrants in Europe live in ghettos with high crime rates (like all ghettos) this has nothing to do with religion. If anything, religion is the SOLUTION to this problem, since all evidence indicates that pious practicing Muslims (and perhaps religious folk in general) commit vastly fewer crimes than non-religious folk. See Javed Jamil's research. So European governments should build mosques and churches and encourage piety.
Fifth: Europe desperately needs immigrants due to its collapsing birth rate. Its economy is going to hit armageddon in a few years unless there are enough young workers to support a population top-heavy with elderly people drawing social security.
Sixth: The percentage of "darker-skinned/Muslim" immigrants in Europe is minuscule. As of 2010, the most recent year for which I can find Europe-wide data, only 6% of the people living in the EU had been born elsewhere, and of those, many were from the US, Canada, Australia, New Zealand, Russia, etc. etc. This is hardly a "replacement of the population" by dark-skinned hordes. On the contrary, it is not even close to enough to pay the social security of the next generation of retirees!
Seventh: The real problem of "European immigration" is not non-Europeans entering Europe, but the other way around. Europeans are migrating and invading all over the world and degrading things everywhere they go, as explained in Andre Vltchek's article Stop Millions of Western Immigrants! which explains: "Tens of millions of European and North American immigrants, legal and illegal, have been flooding both the cities and countryside in Asia, Latin America, and even Africa..."
Eighth: The recent refugee crisis involving MENA countries was 100% caused by the West and its criminal wars of aggression against those countries. The West owes massive reparations to the entire population of MENA. People who want to "lock them out" while taking no responsibility for their own war crimes are the scum of the earth.
So Brandon is seriously wrong on this issue. But he's a smart guy, a great writer and speaker, and a basically reasonable person. (Plus, he is at least partly right about Soros.) So listen to what he has to say, and make up your mind about who's right.
