You may have as promiscuously liberal an immigration policy as you please – provided, however, that the migration is only onto your own land and by your express invitation. In that case, you are responsible for any misbehavior on the part of your guests.
For the last four decades, however, Britain, like America, has had a most liberal immigration policy, except it is not by invitation only and it is all onto “public” land, which everyone owns and therefore no one owns. No one is responsible for the misbehavior of any noninvitees, except they themselves - if you can catch them before it's too late.
If some of them should wage war on you once they’re “here,” because you’ve given them insufficient reason
not to identify you with “your” government - whose behavior in
their lands drives the morally defective among them to indiscriminate, murderous hatred – well, that’s your tough luck. The government says you had to have tolerated these criminals on the “public” lands that happen to abut your private land. If you hadn't,
you'd have been a criminal.
If it is not a matter of indifference to you that, no matter how law-abiding the vast majority of these noninvitees are, they cannot help but gradually transform “Britain” or “America” into a country that is foreign by its own historical standards – why, you’ve just revealed yourself to be a racist, than which form of life there is no lower. You have thereby jeopardized your rights to life, liberty, and property which, in our multicultural paradise, already hang by a thread. So why not do yourself, and the rest of us, a favor by shutting up before someone decides to revoke those rights?
Immigration without invitation is, as Professor Hans-Hermann Hoppe has argued
again and
again, forced integration. It can chafe, it can frustrate but, as we learned today, it can also kill. It is the antithesis of free association. But who does not know that free association is as dead as
Enoch Powell?
