Exactly what I said. You're just not smart. You're not really worth my time and I have nothing but contempt for the way you think.
Why should anyone reading this care whether you think I’m smart or not? Why should I care?
I guess I should feel flattered to have earned your contempt. (Is your contempt a rare prize? Or do you feel contempt easily?)
Sorry for all the questions, but this is a quite strange and amusing experience for me.
