It's worth noting that a good many readers might be ignorant *and* the typical reader. I reckon my books have been read by perhaps scores. Maybe even a hundred. Statistically there's ample room there for ignorant readers.
I'll extend that. My novel A Child of Great Promise begins in the Camargue. I'll lay eight to five that most readers will not know that word, be ignorant that it is a region in southern France, and still fewer would know that there was once a Kingdom of Arles. I sort of relied on that ignorance, for it let me describe a setting and a people at least faintly exotic. Medieval cowboys in France? Ridiculous!
