Back in 2010 after teaching so-called dyslexic kids for 6 years I was convinced that all my approximately 20 students whom I taught during the 6 years were shut-down kids who had disengaged from learning to read due to confusion.
At that time the existing theory that had existed for more than 35 years was that kids could not read due to phonological awareness deficit.
I disagreed with that theory and wrote over 100 articles/comments that disagreed with it until it was debunked in 2017. You may read some of my articles/comments in 2010 here. LINK
