Native Americans did not exist as a nation claiming to own and control the north american continent, some practiced slavery, others were nomads roaming instead of claiming land as there's etc., so overall this is a specious 'argument'.

Native Americans have always had nations - their territories. They've always had leaders, laws and customs.
Many will argue that Native Americans didn't have claims such as paper deeds but I highly doubt it would have made any difference. Conquerors don't care about any claims.
A settlement is a settlement. There was never a legal or moral reason for kicking people out of their land and murdering them. Heck, Native Americans were willing to share.
Funny. Early European settlers also never claimed to own and control the North American continent. There has been slavery, and there has been roaming like nomads out to the Wild West.
I believe the Native American leaders are simply enjoying the irony. The "illegal European population" didn't have a problem with immigration until many of them decided they didn't want 'others'.
