"By the time I got there in the 1970s, pretty much the radical activity had abated," Bustamante said. MEChA helped him become one of the first Latinos in the student senate and backed him in an unsuccessful bid for student body president.
Nice whitewash job. So to speak.
That same quote is on the current MEChA sites you linked to earlier today, which is noticably more recent than 1969. They're trying to present MEChA as a formerly radical group that long ago became mainstream. Deleting the online evidence to the contrary is clearly part of the plan.

From "El Plan Espiritual de Aztlan"
In the spirit of a new people that is conscious not only of its proud historical heritage but also of the brutal "gringo" invasion of our territories, we, the Chicano inhabitants and civilizers of the northern land of Aztlán from whence came our forefathers, reclaiming the land of their birth and consecrating the determination of our people of the sun, declare that the call of our blood is our power, our responsibility, and our inevitable destiny.
We are free and sovereign to determine those tasks which are justly called for by our house, our land, the sweat of our brows, and by our hearts. Aztlán belongs to those who plant the seeds, water the fields, and gather the crops and not to the foreign Europeans. We do not recognize capricious frontiers on the bronze continent
Brotherhood unites us, and love for our brothers makes us a people whose time has come and who struggles against the foreigner "gabacho" who exploits our riches and destroys our culture. With our heart in our hands and our hands in the soil, we declare the independence of our mestizo nation. We are a bronze people with a bronze culture. Before the world, before all of North America, before all our brothers in the bronze continent, we are a nation, we are a union of free pueblos, we are Aztlán.
Por La Raza todo. Fuera de La Raza nada.

Note in particular how this directly contradicts the lie in the article that MEChA "did not seek a separate political state."
