This might be a question of “Culture” vs. “Race” but one of the more problematic aspects of this is the Raw Explosion of Population.
First, most if not all of these people have no intention to assimilate into whatever country they go ... they force their way into.
Second, as horrible as their lives are, as deprived as they seem, they simply Don’t Stop Making More ...
It’s all very illuminating to say 6,000 people a day are coming in ... by whatever means ... but putting that number on the problem seems like maybe if you allow another 6, 600, 6,000, 60,000, 600,000, 6,000,000 ... that the “flow” will slow down ... will stop.
There’s an old saying about China that, if you lined the Chinese People up shoulder to shoulder, 5 or 10 abreast, and marched them off a cliff ... the Line would NEVER END.
That was many decades ago and that saying can be easily applied to the situation now to this “crisis”.
People can say whatever they want, they can point to the “humanitarian” aspect, they can point to their unwillingness to assimilate, they can point to the Quality of Life these people are leaving, they can point to ANYTHING they want ... it WON’T Change the Underlying Problem ...

Whether it’s Europe with Middle Eastern or Sub Saharan or Indian Asian or even Southeast Asian ,,, or the USA with Hispanics and all sorts of Other Nationals ... Whether they call themselves “Refugees” or “Immigrants” ...

There is a HUGE Disparity in Their Current Population AND in Their Population Growth Situation ... no matter how Bad it might be wherever They’re Coming From ... They CONTINUE to Make More ...

Europe and the USA are seeing just the Relatively Small Waves of a Quickly Rising Tide ...
Accept as Many as You Want, behind EVERY ONE of them is Another 5,000 or more and by accepting that ONE you become a Beacon to the Other 5,000 ...

He's absolutely right. Thinking that a European society can somehow absorb so many people from so many parts of the world--and that it will somehow turn all these immigrants into Europeans--is a fantastic illusion. It's also very arrogant. No European culture is strong enough to absorb the 3rd world (and its problems) without becoming a 3rd world country. British culture is becoming subsumed underneath the regressive violence and intolerance and fractious tribalism. England is not doing the world a favour by changing itself to accommodate everything and everyone. Multiculturalism without integration is a failure. Slow down immigration. Demand integration. Uphold your own culture, your values, your institutions.

Murray is one of the few authors / commentators who presents an objective balanced viewpoint of the immigration problem.

My views:
All "races" (in reality, humanity is a single race) can coexist peacefully and harmoniously. Immigrants from all "races" should be welcomed.

Not all cultures can coexist peacefully and harmoniously. If a culture's ideology requires the subversion and replacement of other cultures, then that culture needs to be rejected and vigorously opposed.
