Even if your "theory" were 100% accurate, that in no way justifies the genocidal land grab by European settlers and the US Government.
Ok so what do we do 200+ years later to correct the situation? I have heard no suggestion from you. I ask if we should all leave and you refuse to answer that question. I hear no suggested solution coming from you at all.
You ask "what do we do?" about something that YOU have determined is a problem.
I see no problem at all. To the best of my knowledge, no one is demanding the continent be returned or for all "non-native Americans" to leave, though who in their right mind could blame them? YOU'RE the one making those ludicrous suppositions. No one else is.
Leave them alone, if you don't like their policies, politics, taxes, liberties and so on, then get off their land just as you would if you didn't like the laws, rules and rights of Texas or California. There's no correction needed.
What's so difficult to understand about that?
Everyone's entitled to their own opinions, but not their own facts.
