It's called being "obtuse" JJ and the Dims have it down to a science.
Heh. I remember my Mommy saying I was being obtuse when I was about 7 and when I asked what it meant she said go look it up. When I looked it up and saw it meant "willful ignorance" I got upset that she was calling me ignorant. I couldn't figure out why she started LAUGHING. Imagine, an ignorant 7 year old who can go and look up obtuse in the dictionary.
