Anyone can rent a building and start their own dojo, regardless of their experience and knowledge of aikido. They can exaggerate on their qualifications to teach and a person new to aikido can be easily mislead. I feel sorry for the gullible students of these type teachers. I also feel frustrated that they are representing aikido so poorly. Some people go to see aikido for the first time and will leave thinking that aikido is BS.
Sometimes a student moves to an area where there isn't a dojo and must start their own in order to keep training. In these situations, I think that it is okay to teach as long as the sensei and the students continue to learn from a parent dojo. I think that the sensei owes it to themselves and their students to continue to learn.
What are your thoughts?
