Lucky Morales is a gang activist in San Diego. Here he refers to Chicano / La Raza racial and ethnic supremacy. This occurred just before a group of pro-Americans were scheduled to have a American-flag waving event in Chicano Park in San Diego. The message appears to be that non-Raza do not belong in the park and that they should be physically attacked and driven out of the park, which was exactly what happened. Chicano Park is known as an anti-American park, where waving the flag freely is not tolerated.
The La Raza concept was developed by a well-known, Mexican politician and philosopher, named Jose Vasconcelos. The concept is described in his book “La Raza Cosmica”. It is a racial supremacy doctrine for the mestizo race, that is, the Hispanic mixed race.
The La Raza concept is similar to Nazi racial theory, adapted to the mestizo racial environment in Latin America. Vasconcelos was actually the most important pro-Nazi propagandist in Mexico, during WWII. Vasconcelos published the pro-Nazi propaganda magazine Timon (the Rudder).
