The complaints are usually made against the training methods not the moves. Aikido moves are hard, the training partners response is usually rehearsed, and there’s much less focus on competitive sparring. It’s hard to learn something for real when the reactions are rehearsed. Other self defence focussed martial arts (Judo, Brazilian jiu-jitsu) have a lot more emphasis on live sparring. I’ve done all three at different points in my life. Only as a jiujitsu practitioner am I confident that I could handle myself without injuring the other party.
