The more Americanized hispanics will become "white" in the same way people see asians as "white": mostly harmless citizens who exist in an ambiguous state that allows conservatives to bludgeon nigger lovers for their pets' lack of self-control while those liberals bash back with cries of "racist standards". They won't be seen as white, but they'll be seen as easier for whites to associate with. The brown ones will be seen as lesser, but still defined against negro behavior.

Regardless, assimilation of asians and non-White hispanics into White society doesn't actually help White Americans much. It still marks the decline of Whites in America, and could possibly accelerat that decline. It may help against further degradation on behalf of negroes though.
