the meme "Aikido sucks" will never gain enough traction to overtake the meme "Aikido works" since there are 60+ years of multimedia and facts to support it.
60+ years of multimedia?
I've never yet seen aikido being employed (successfully or not) against a live opponent. I've looked into DeLucia; he himself at most says he's used a couple of techniques. Meanwhile, he's pretty much the only one. I've seen that "Muay Thai Vs. Aikido" video, but that's light sparring at best; cooperative showboating at worst.
This is the central empirical problem. I can believe it working -- absolutely. But I have little evidence other than my own experience, which is mixed at best.
