Only sort of a joke. Irony is lost on these people. The UK actually bans people (Michael Savage as an example) right now...but they take umbrage when Trump suggests it here.
If I were told that I was banned from entering Britain, I’d reply that’s like being told that I can never visit Pakistan.
The Brits must be really full of themselves to think that the worst punishment in the world is to be refused entry to:
“This royal throne of kings, this scept’rd isle,
This earth of majesty, this seat of Mars,
This other Eden, demi-paradise,
This blessed plot, this earth, this realm, this England.”
Not bloody likely, mate.
