Perhaps we could use a bit of a qualifier here.
I do believe that people are doing the best they can given who they are and what they are there for.
Some people just don't have high expectations for themselves or Aikido.
But, there probably is some positive intention that they are showing up and training.
This reminded me of something I realized many moons ago. Students go to learn and a happy student is one who is doing so. Therefore all students should be having fun for good study and practice is fun.
Now it's not so much the students who should know this rather it is the teacher. In other words it's the teachers responsibility to make sure progress is being made in a good atmosphere.
If anyone wants to be super disciplined about this then I would say use this rule: 'It's never the students fault.'
