A blind person is not a good bus driver. A physically impaired person is not a good mover or yoga teacher. A deaf person is not a good session musician. A person who cannot function sitting in a meeting with 3 people for an hour is not a good employee where that is required. What makes the last one special compared to others? They can be a great yoga teacher/bus driver/session musician/mover, I just don't see controversy

Simple accommodations can be made if needed and then there's no need to exclude people on old-fashioned prejudice.

maybe there is a company where being an amazing programmer is enough. I worked with capable depressed programmer who never delivers and is too shy to delegate anything, capable psycho programmer who no one wants to work with, bad programmer who works crazy hours, carries the project and interacts nicely with customers when needed. The last one was probably the most valuable

I mean... that's what the title and context of the discussion thread is all about?

Just because they are physically impaired now doesn't mean they were before, and an instructor won't necessarily move through the poses with the class since they can have 2-3 classes per day.
