I personally don't care for it when someone calls someone else stupid, less intelligent, etc., because they don't happen to agree with them.
What is really stupid to me is when someone doesn't understand something and asks for clarification and then is accused of being stupid for not understanding in the first place. Seems to me, the least stupid thing to do is to ask. At least that sounds pretty intelligent to me.
Intrepid,

You are on a roll today!
