Geeks find the constant back-and-forth of corrections in dialogue to be interesting and educational. Non-geeks do not; they lose interest by about the second iteration, and will become annoyed shortly after.

Little Edit: if you think describing 'I don't agree with you' as an 'altruistic desire to educate' and single-handedly preserving the 'validity of discourse' and the 'truth and correctness of human understanding of the world' is anything short of absurdly presumptuous, you might want to re-read the linked article very carefully.
