The USA is a settler state, tf are you talking about mate? Or does it require someone from a ex-colony to explain you the what's and how's?
Ecocide? Very much visible, many lakes and forests have been destroyed and polluted, lands have been turned into concrete jungle of highways.
Linguicide? Obviously, no one speaks and practices the language and culture of the native Americans in their own land. Can you? No, English is not their language.
Apartheid? Areas where the native Americans live are very underdeveloped. Their right to vote is suppressed. Access to healthcare is abysmal. Isn't that apartheid?
Poverty? Yes, the Native American is the most impoverished groups in the USA.
Political representation? Almost nonexistent compared to other groups. Name a few popular native American politician, I'll wait.
Right to self-determination? Most of their lands are under the control of imperialist white men and their crony capitalist buddies.
The USA is the most unhinged form of evolutionary neo-colonialist project, a produced of primitive capitalism gone rogue and rabid, mimicking the "success" of the East India companies by colonizer European states. Death to imperialism, death to America.
