Do you think it's wrong for a man or woman to date someone who's dumb?

Sorry, your question gets me angry. My mom couldn't write nor read, and her marriage to my dad was disapproved from the very beginning by my dad's parents. My maternal grandfather was the kindest man who I've ever met. Now my guess is that they also had both dyslexia like myself, and that was the actual cause for their so-called dumbness. So-called, of course, because neither lack of learning nor intelligence is something dumb
