I don't feel offended and no intended to bash Mr Author, because i have usually bow to shomen but O Sensei's potrait without clap my hands. I know that such misunderstanding is too deep until can't corrected, especially to some of Christians/Muslims without any martial arts. I had been asked by my churchmates regard a faithfull Christians become good martial artist, and some of them are don't really know that metally fact regards Chuck Norris martial arts grandmaster as a Christian as well as an entertainment star.
Simply, i do really respect to O Sensei and apperciate his works at his lifetime but i don't worship him as kami. Logically, bow to each others is necessary among Japanese culture and evenly Aikido Dojo. I don't fell that i am worship each others with my sensei or Aikidokas else, is it illogic that a kami worship to another kami? And how about Japan national flag? It will be sensual if only Japanese flag displayed at foreign dojo, because it considered as cultural attack. But it doesn't matter if both American and Japanese flags displayed at an American dojo. Perhaps that some normal Christians or clergies don't really understand that what is Aikido, but it is effects to the community and perhaps that non-Christians misunderstand about Christianity.
BTW, this is my personal testimony. I know that someone will pisses me off here, i don't ever call myself wiseful person or i am holiness.
Have a nice day my
