You forgot to include ignorance and pandering. One interview I saw between one of the talking faces on CNN and a former NASA engineer absolutely disgusted me. The engineer, who was trying to give a little background on rudimentary mechanics and aerodynamics of suborbital flight, was continuously cut off by the face who haughtly said, "you just lost most of the audience." What did the audience get lost over, you ask? Oh, just a couple of things most folks should have learned in high school: F=ma and KE = 1/2mV2.
The terms haughty, condescending, and arrogant come to mind. (Not to mention unjustifiably. :)
