This isn't the agenda of most of even the most radical folks of La Raza & Company. In that most Mexicans and Central Americans identify with a Hispanic culture (as does La Raza and most of the other neo-Marxist Hispanic organizations), this little fringe group is really out in the wilderness, denouncing La Raza and other Hispanic-oriented organizations.
If we're going to get hysterical about someone, these aren't the folks about which to get hysterical.
What you say is probably true, but who is to say what the agenda of the more 'mainstream' groups will be 30 or 40 yrs from now?
Por La Raza todo, Fuera de La Raza nada - "For the Race, everything; outside of the Race, nothing."
MEChA stands for Movimiento Estudiantil Chicano de Aztlán, or Chicano Student Movement of Aztlán.
MEChA exists as over 400 loosely affiliated chapters within a national organization.
