Of course it should also be noted that a large number of Hispanics by then will have forgotten their language and look and behave exactly like whites.
Not "forgotten" their language; they will be second- and (especially) third-generation immigrants who may have grown up speaking English exclusively, or at speaking English fluently from a very young age. This is not exceptional, as it's what happened with every major immigrant group save those which already spoke English (and even the Irish had the multi-generation assimilation of replacing Irish accents and idioms with American ones).
