Are you serious? Do some research on the flight of British Loyalists to Canada after the American Revolution. Do you think any of them would have their land titles from King George III honored if they came back today? LOL.
Did every Loyalist flee? The answer is no. At least 1/3 of Americans remained loyal to the King. America did not lose 30% of it’s population. Those who chose to stay were not well respected after the war, but their property was not sized and they weren’t thrown into prison camps either.
