Can you please help me understand this?

Ok here is the scenario you have two people having a discussion and one is more knowledgeable than the other on the subject! The one lest knowledgeable calls the knowledgeable one crazy or they have a mental illness? Or scenario 2 A man is having a convo with a women but the women is more knowledgeable on the subject than the man why is she labeled as being mentally ill cause she is more knowledgeable
