You're confusing intellect with intelligence again. Intelligent people have character regardless of their IQ. Matter of fact, you might say that the presence of one is synomous with the other.

People with a high intellect do not necessarilly have common sense.
Any other straw men you'd like to beat?
So an intelligent person with an IQ of 40 has character. Got it.
Now who, besides you, defines a person with an IQ of 40 as "an intelligent person"?
