Chiapas gangs = "war-painted tribes"?

Don't compare Mexico gangs to American IndiansThis is in response to J.P. Devine's review of "Sin Nombre," which I went to see with my wife in order to check the Spanish translations about "the fetid landscape" of Chiapas, Mexico, a "Mexico no American ever Sees," dominated by gangs that are "little more than animals," tattooed poisonous flowers straight out of the darkest gardens of hell.

According to Devine's review, the members of Chiapas gangs are "so covered with tattoos" that "they resemble the war-painted tribes of the great prairies. So mutilated are they, they could not possibly interact in modern society, so they push drugs and prostitutes among their own suppressed people."

I find it difficult to understand Devine's comparison between the war-painted tribes of the great prairies, and the tattoos of the Chiapas that makes the tribes unfit to possibly interact in modern society without pushing drugs or prostitution.

And, lest we forget, we know how Hollywood stereotyped the tribes of the great prairies into "painted savages."
