What consolation to the Native Americans is it that all in the U.S. call themselves American?

According to the Office for National Statistics it's estimated our population increases by a million every three years. Third world immigration and their high birth rate accounting for three-quarters of it. (Though this will increase exponentially rather than by a simple million each time of course.)
Why are we English more scared of being called racist than talking about how this situation has an ultimate, terrible consciequence if not stopped?
Is calling black men English their way of countering the claim we English are in danger of extinction?
The new Equalities Bill allows non-white preferential treatment and monies to go to 'minority' only organisations so unless there are different 'levels' of Englishness the law itself treats us differently.
Put simply: what consolation to the Native Americans is it that all in the U.S. call themselves American?
