I have another ancestor who was on the Mayflower — left England behind because of interference from the Government, and here we are 392 years later come full circle - on a thread discussing leaving the country because of Government interference onto our rights and liberties.
The rights and liberties you speak of, have only been enjoyed by Americans these last 236 years because someone stood up and fought for them to begin with. They were never given to our people.
If you think the solution to the erosion and possible loss of those rights is to flee, then by all means, go. Maybe you'll find a new country, run by a benevolent dictator who grants you all the freedoms you're unwilling to fight for.
