Disagree.
England preexists the First Amendment, it is quaint to think nations should adopt policies at the request of visiting guests.
As a US citizen, I discount any condescending ‘recommendation’ from foreign guests.
You and I are in some agreement, CharleysPride. I think the difference is just who is the nation Trump’s message would be for? I think you see England’s “nation” as her leaders, which would hate that message. While I see England’s “nation” as her masses, most of which would agree wholeheartedly with that message. So the way I see it, the message would be confirming the U.K. nation’s desires.
