The linked blog is by a notorious America-hater Umair Haque, almost all of his pieces are slammed for similar reasons you see in this comments section. It's hate bait, nothing more. (I recommend "Why the Anglo World is Collapsing" /s) Take a look at his other work to get an idea of how seriously you should take this guy: https://eand.co/@umairh
[but please look at the actual article, not the link in the header· NB: I have no knowledge about the author other than that article. But the article is what's being discussed here.]
He is, for example, pointing out that history shows that the way to progress is by "lifting one another up, not keeping anyone else down" and rejecting the "I rise by pulling you down" philosophy, which is exactly the reasoning of the groups that are currently destabilizing factors in some Europan countries.
In other words - it's the opposite of hate bait.
