The idea that nobody thought any of this through is an extraordinary admission… If you are having problems integrating people when immigration is at a relative historic low, why would you think you could do it better when it’s at an all-time high? […] It’s an odd thing to do, societally and culturally - to, for instance, without any mandate from the general public, decide to become something totally different… It’s an odd thing - for a society to effectively decide to abolish what it has been hitherto, and to become something totally new.
Douglas Murray, speaking recently in Norway. The talk begins around one hour seven minutes in. Via Simen Thoresen in the comments.
