Very interesting comments and I think what you wrote is very important for different learning styles. I would in no way consider it a "disability" rather a non-verbal learning ABILITY.
Funny enough that my friend, that I stayed with over the weekend, and I had a similar discussion about differences between people. She is a math teacher who had to give up teaching due to a disability. She's started teaching spinning classes and I went to one of her classes. The owner of the fitness center has a different opinion of how she SHOULD teach. For me, she was the perfect style. I can understand that he does not appreciate it but I feel that he misses the larger issue. Neither of their styles are absolutely right or wrong. It's a fact that people learn differently and he should be glad to have someone who differs from his style, IMHO.
I also have to laugh about the comment from xH. While I did not grasp how fully xH did not understand himself (and did not know he was projecting), I did understand that he was deflecting when he did that and he knew that I knew Humor really served us well in the early and midyears of our relationship. Good or bad we still had a lot of fun even with our dysfunctions!!
