There once was a well named nation called Great Briton. Alas, the freedoms she offered died on the alter of political correctness.
And I’m afraid we’ve got some folks in high and influential positions in the USA who are busy building the same PC altar here.
Its Great Britain. Briton is a person who is from the nation.
BTW, as to your point, please see my reply to the others in this thread. Saves me reposting.
