Cuz in a different thread he corrected when I typed "U" and replied "*you".

Totally pedantic and annoying

And he keeps saying "read again"

Totally annoying. I also told him to rephrase

When I said he's using text-to-speech I don't mean he's blind, I mean he can't read.

I reached common ground with him that diagnosed dyslexic people should get special treatment and I extended it to other unrelated skills like reading analog clocks (in biology exams). You, on the other hand, make fun of dyslexia. What context did I miss? Is ablism ok when the butt of the joke is an asshole? If the conversion was about whether dyslexic people or non native speakers should get extra time or something, would you be team "nah, they are just stupid"?

Have you learned the clock yet? I suggest learning how to read with understanding now.

Read again. Slowly.
