Unknown Enemy
Well, I sure hope you don't ever become a lawyer - "Your honour, my client is clearly not guilty, because all the witnesses for the prosecution are stupid!"I'd rather say the person with an opinion like that is stupid.
Ah... hen and egg thing I guess.
A person can have a stupid opinion without actually being stupid - and more to the point, he can have a wrong opinion without being stupid, simply by being misinformed. How you react to this usually determines on whether you can persuade him or not. As a general rule, when you call somebody stupid, you lose any chance of actually changing his mind on anything, because people don't listen well when they're being insulted.
