As far as I know, his claim about what these societies believed is false. And it's impossible to prove a negative, so his plan was doomed to fail. But because he deemed non-Western societies primitive and superstitious, he earned a Stereotype of the Month nomination.
Correspondent Al Carroll, who brought Macaraeg to my attention, added this note:
I checked around. No such thing. The instructor later admitted he had picked it up in China. Still, the site owner, Ruel Macaraeg, claims Lozano is "enormously influential" and so will be included even though Lozano admits to being a fraud. Maybe you could include two nominations, one for Macaraeg and one for Lozano.
Lozano speaks up
Recently I received this e-mail from Lozano, whom I hadn't heard from before. Nine years after the fact, he wanted to set me straight:
I ran across your website and you mention my name and the martial art of Yaomachtia and you say so many things about and some Ruel Macuareg whoever he is.
I don't know either one of you and neither one of you know me. I don't appreciate your comments about me or this ancient martial art i teach.
Why don't you research correctly what you talk on your so-called website before you talk about it.
You don't know anything about the Pre-Columbian Martial Arts to be making your unbased comments.
Ask and ye shall receive
I Googled yaomachtia once again and sent Lozano this reply:
Sorry, but I don't need to know you to comment on something I've seen in the media or on the Web.
>> Why don't you research correctly what you talk on your so-called website before you talk about it. <<
I did research the subject before talking about it. But I'll update the research now. Here we go:
It was indeed a martial formation but nothing like a martial art.
If you want to send me the missing evidence of yaomachtia's use in Aztec times, go ahead. Be sure to include authoritative sources for all your claims. Don't simply cite your own publications and videos. If the claims are credible, I'll update the page.
Needless to say, Lozano didn't respond to this e-mail. He has yet to provide a shred of evidence about yaomachtia's existence. The yaomachtia.com website is now defunct.
If Lozano comes across this posting next, my offer still stands. Go ahead and prove yaomachtia's existence to me. Put up or shut up. Until then, I'm still comfortable labeling it a "fictitious" martial art.
