Why do leftists hate that Europeans immigrated to America when the Indians were here, but support unfettered immigration now?

The Indians should have built a wall and implemented strict immigration policies. But they couldn't, because they didn't even have a written language, or any form of national government. You can't buy land from people with no land titles to sell, and don't even know who the land belongs to.

The Europeans didn't take the western hemisphere from the indigenous people, reality did. What moron thinks a whole half a planet of primitive people are going to have the luxury of staying that way due to squatters rights?

Africa is still trying. I don't know about you but I'd rather live in America than Africa, regardless of how my ancestors got here. Some people here have ancestors who died in gas chambers less than a century ago. So save me the sad stories about what you think might have happened in the fucking 1600s.
