Not bad, Mark… except at the end, where I suddenly went into Lou Costello mode, going “Eee-eee-eee!” through clenched teeth and grabbing my hat so it doesn’t vibrate right off my head.

[You] “So don’t delude yourself: If the English and Scots and Belgians and don’t want to have children, it won’t mean a return to bucolic pastoral vistas, it will just mean the places of the kids you never had will be taken by immigrants.” It will only mean that if the English, Scots and Belgians let it. [You] “If Yemen cuts its fertility rate, Yemen will empty out. If Britain cuts its fertility rate, Yemen will move in.” Only if Britain lets it, Mark. This is Tamar Jacoby territory you’re lost in here: Mass immigration (argues Ms. Jacoby) is a force of nature, like continental drift–nothing you can do about it, futile to try, driven by irresistible economic forces, etc., etc. But that’s all nonsense. How will those Yemenis “move in,” if Britain refuses them entry? And why should Britain not refuse them entry, if British people don’t want them? If Japan, which actually has a declining population, can set its face against mass immigration, why can’t Britain? Why can’t we?
