Nobody can make dyslexia or any other learning disability go away. I know this because I have multiple learning disabilities myself. I've lived with them all of my life so far, and I will continue to live with them for the rest of my life.

What can be done is to help people find ways to compensate for their learning disabilities. I have not seen the poster with the dyslexic child say that their child has not learned how to compensate for their dyslexia, so the accusation that they have fucked up with their kids seems pretty spurious to me.

And as I said above, many schools don't help kids with learning disabilities learn how to compensate for them. Some of them just don't care, some of them don't have the budget or enough staff, and some of them think they know best and in their judgment, it is the fault of the child and/or the parent that the child is not performing up to the standard that the school thinks they should.
