I couldn't agree more but very few people knows the truth about the Black Legions in South America, and his zine won't be filled with that subject entirely which is obvious, a zine is meant to support newer bands but an article about other subjects from time to time is not wrong, I think. This article will represent maybe less than 10% of the zine, so why not?
Maybe it would also be the occasion to explain that the Black Legions are totally overrated and that all these bootlegs popping up are silly, also I have big doubts about the true existence of some of the so-called side projects they had, etc...
K.A.'s request is for people who are OK to write something about that, that's all. I refused to write anything about that, just like you refused, and for the same reasons (you can ask him). But I don't see any reason about stopping K.A. to do this article.
