This kind of flawed thinking again. Like the natives didn't fight and lose wars against the manifest destiny types.

I don't think anybody claimed no Native Americans tried to fight back against their genocide?

It's painting border enforcement as somehow immoral. There is no sin in trying to be better at it than those before.

genociding people to take their land within their borders is generally frowned upon today

If only they were better at border control, maybe they wouldn't all get killed off.

yes, generally it is frowned upon today to genocide people and take their land within their borders
