Here's a video by one of those neo-indigenocentrics named Carlos who negates hispanic and/or latino identifies in favor of indigenous and/or afro-based hypodescent:http://www.youtube.com/watch?v=s-aJTWgdufc
He does raise some interesting points as to why these terms are problematic, but he negates (or denies) the fact that most of the people he is talking about are of mixed "racial" ancestry and come from closely-related hybrid cultures that generally have Spanish heritage as a common root.
Here's a video where we can see some of his handiwork. He questions several Latinos as to which "race" they self-identify as ("white," "black," "Native American," and/or "Asian") and basically pronounces them as being in "denial" because they don't self-identify as Native American, even though most are clearly of mixed "racial" ancestry and identify with their Spanish roots to some degree. http://www.youtube.com/watch?v=3e6ChgL1 ... r_embedded
Notice that his method of questioning is misleading, as he does not ask them if they have indigenous ancestry (of which he might have gotten some different responses). He also does not ask any of them if they have multiple ancestries, even though its obvious just by looking at them that they're mixed.
Here's another video where he labels Mexican-American comedian George Lopez as a Native Mexican (Native American), taking no regard for how George Lopez may, or may not, self-identify. It is also worth nothing that, having taken a DNA test, Mr. Lopez's genetic results came back with 55% European genetic markers/admixture. http://www.youtube.com/watch?v=a0tthpO5vzQ
