Bowing, in and of itself, cannot approach religious reverence. That requires intent, not a simple movement of the body. Given the cultural context (it's just a very formal show of respect), it's only worrisome if you ignore the intent behind it. This approach could also lead someone to see an enthusiastic, 2-handed handshake as a display of domination.I agree. I considered studying Aikido, but was worried about the bowing I saw on some TV documentaries, which I thought approached religious reverence. I probably should have actually visited some schools and watched, and asked questions. I might have found no reason to worry. Or confirmed my earlier observations from my religious viewpoint.
