Silly is as silly does. Fear and ignorance guides those parents. As a parent I don't want my girls bowing to anyone or anything. But of course, I don't mind a handshake.
BTW where is the god in Aikido? I can't imagine where they would see a god. Fear & ignorance.
Faith, welcome to Atheist Nexus.
I like the idea of Aikido. Being in control of an attacker with out needing to be on the attack fits my disposition. I took boxing in my younger days. I always had trouble being the first to attack.
