an interesting post - you raised the idea of prejudice towards wearers of glasses and it brought to mind a personal experience.
I was teaching and one student interrupted me by exclaiming out loud - 'See - he does wear glasses!' This was a student who was very anti-intellectual to say the least. He despised what he called four-eyed geeks.
I shook my head sadly. "Are you that superficial, Garth?"
He shrugged. I pulled my sunglasses out of my suit pocket. His girlfriend smirked and elbowed him in the ribs.
Paranoia runs deep :)
Why ever, then, was he a student at all?
