Turning into a good thread
Respect is a 2 way thing, training at another Dojo along side you core style is not a reason for disrespect.
The mass walk out to me is an issue as to what kind of Instructor your Sensei is. there must have been some kinds of discussions prior to this happening.
For me I keep my Dojo separate from my work life, my family life and my Religious and political views as I am there to teach karate NOT dictate where they work, who they are in relationships with, how they worship or who they vote for
A man is but the product of his thoughts what he thinks, he becomes.
