I didn’t call you ignorant, and I’m sure you wouldn’t call me ignorant, either. Have a good ‘un.
I doubt you have any idea of the history of the crown of thorns, of the Sainte Chapelle, or of Notre Dame. You seem to enjoy casting doubts out of hand.
I can call myself ignorant; for I know that it merely means that I am unknowledgeable about something or other.
Once the facts of the matter are shown to me; I am no longer ‘ignorant’.
Now STUPID means something else. Like I am incapable of learning or retaining data. Or willfully reject it.
