Of course they do, but you'll never hear about them. Opinions are given weight by numbers, not abstract ideas like when your ancestors arrived.

How do you think they look back on their forebears, who failed to preserve and pass on their birthright?

I suspect they would have preferred to prevent immigration entirely, though I cannot speak on their behalf.

This seems like whataboutism. The treatment of Native Americans isn't really similar to modern voluntary immigration and integration.

Sounds like the integration might be at effective gunpoint (threat of deportation) and not entirely voluntary.
