Dyslexics don't demand that we change the structure of the English Language though to fit around their learning disability.
Whereas some in the transgender community want to turn science and biology on its head to accommodate their belief - and censor anyone who doesn't agree with them.
This is the crux of the matter for me. Dyslexics have no impact on anyone else, and make no demands on others. They don't picket libraries or reading groups, screaming at others for meeting without them. It is a totally false equivalence, and I really don't want to get involved in what will end up being a string of 'Gotcha's when I put a foot wrong.
FWIW, I can understand people wanting a diagnosis ion something in later life. It may not change anything, and yes, we are who we are, but if someone has gone through life being called lazy and disorganised and assuming that to be true, it must come as a relief to be told that actually they have ADD. Whether that matters on a practical level or not, it can only be a boost to their self-esteem. As with so many services, however, the numerous cutbacks make that diagnosis difficult for many people.
