Moreover, there is simply no evidence that at the time Bustamante participated in MEChA that it espoused the kind of naked racism and virulent anti-Semitism as can be found in La Voz. Nor is there a smidgen of evidence that Bustamante ever held such views or endorsed them. The best that Ponte can do is to demand that Bustamante publicly disavow such groups.
This is, incidentally, precisely the kind of "guilt by association" of which right-wing characters like Horowitz and others regularly accuse the left and civil-rights organizations like the SPLC. But unlike the associations that the SPLC finds, say, between mainstream Republicans like Trent Lott and neo-Confederate organizations, the evidence to support such linkage is not only extremely thin in Bustamante's case, it is nearly non-existent.
It probably would help clear the air if Bustamante were to make his position regarding La Voz de Aztlan unmistakable.

Though I did cite Carreon and Cienfuegos's La Voz de Aztlan as "Mechista fellow-travellers" -- an entirely accurate description -- I did not state nor imply that Cruz Bustamante was directly affiliated with or even sympathetic to that publication. Furthermore, I specifically disavowed Lowell Ponte's hypothesis of Bustamante's hidden agenda. Finally, the piece itself contains a glaring factual error: While there is indeed no evidence, to my knowledge, that MEChA harbored anti-Semites during Bustamante's active association with it, the statement that it did not espouse "naked racism" at that time is simply false. Such racism is at the core of its founding, and plainly evident in its constituting documents.

2) On topic: Indeed, Bustamante may have been a Mechista, it is probably likely...when was he a mechista, and what were the activities and politics of the mechistas at that time? What was his participation? Did he write for them? When did he disassociate with or drift away from involvement, and has he been involved since? Has he ever espoused any political lines that could be attributable to or akin with mechista politics
Just questions all. I only know 1.5 answers. The 1 answer is that the Mechista ideology was thoroughly racist from the get-go in '69, as evidenced by its founding documents cited above; that hadn't changed by Cruz's college years from '73 through '77. The 0.5 answer is that aside from endorsing illegal immigration, I don't know that Cruz has espoused any Mechista policies since then.
...What's absurd is your comparison of MEChA to Nazis and the Klan. Until you can prove a pattern of systematic murder, torture and racial violence....
Quite obviously I'm not making that comparison of scale; nor am I asserting that "Chicanismo" as espoused by MEChA is as inherently evil as Nazi or Klan ideology. Re-read that portion.

What's So Bad About Arnold Schwarzenegger Anyway? Schwarzenegger's reputation, meanwhile--which I've heard from one reliable source, one eyewitness ultra-reliable source, and one unreliable Premiere article-- is this: He bullies people "below the line." That is, he bullies the technicians, costumers, etc. who aren't billboardable talents. Is it to get his way? No--he's the star and he's going to get his way anyway. It's from an ugly sense of pleasure in others' discomfort. ... Will this unpleasant character trait come out in the campaign? Schwarzenegger may learn, as Howell Raines learned, that it's harder to get away with being a bigshot prick than it used to be. ... On the other hand, if I were being hounded by investigative journalists, I'd sure want them to be investigative journalists from the L.A. Times. The Times' record of failing to destroy its targets is legendary. Under its new management the paper is better than it was, but culture is hard to change....

La Voz de Aztlan understands and greatly sympathises with Mel Gibson and his present predicament. The two Jewish organizations that have vehemently attack him, the ADL of B'nai B'rith and the Simon Wiesenthal Center have also attacked us. Both organizations have written extensively against us simply because we are Christians and because we dare to write the truth in articles such as this one.
