‘For some reason, British Monarchs don’t like being reminded about 1776. Why is that?’
Is it the same reason that Americans don’t like being reminded that if England hadn’t settled America and then spent 150 years protecting the American settlers from the French and Spanish, you wouldn’t have had the chance to join forces with the French and rebel? ;-)
The American West was settled by Americans - Not by a bunch of woossies with their pinkies in the air.
