"I think that you finding it funny I judged bits of this thread to be disablist, is to do with you finding the subject funny."
That is all in your head. It is funny because yours is a knee-jerk reaction and had nothing to do with the OP, who wasn't being disablist at all.
"I accept we disagree here, but it is disagreement."
Disagree?
You misunderstood what I wrote. I tried to correct your misunderstanding. You refused to understand your mistake, although I have written it correctly, with proper spelling and punctuation. There is no disagreement here. There is only your dog-headed refusal to say "Sorry, I misunderstood".
"And yes, this is my usual level of reading comprehension. I'm sure it doesn't genuinely shock you."
It does genuinely shock me. I'm sorry. Let us know in a year or two how your Oxbridge undergrads feel about it, too.
