The motto Tancredo's referring to seems to be a mistranslation of a slogan of sorts from the 1960s:"Por La Raza todo, fuera de La Raza nada," meaning, literally, "for the race [or community], everything; outside the race, nothing."
It's a line that appears in a 60's era manifesto called El Plan Espiritual de AztlÃ¡n, which was influential to members of a separate group called MEChA (Movimiento Estudiantil Chicano de AztlÃ¡n). Several decades ago, MEChA was a fairly radical student organization, whose mission was to return the lands of the southwest United States to Mexico--an idea called "reconquista." Since then it has become, basically, the equivalent of a Mexican Students Association at most colleges across the country. ]
MEChA, as it happens, does have a motto: "La UniÃ³n Hace La Fuerza", meaning, basically, "Unity Makes Strength."
NCLR's website is pretty clear about reconquista.
Another misconception about NCLR is the allegation that we support a "Reconquista," or the right of Mexico to reclaim land in the southwestern United States. NCLR has not made and does not make any such claim; indeed, such a claim is so far outside of the mainstream of the Latino community that we find it incredible that our critics raise it as an issue. NCLR has never supported and does not endorse the notion of a "Reconquista" or "AztlÃ¡n."
These are the sort of ambiguities that I suppose you miss, if you can't tell the difference between a motto and a logo, or MEChA and NCLR, or, dare we say, people of Puerto Rican and Mexican descent.
