I wasn't getting TECHNICAL about this as you are. Bottom line and simply put is, a Genius is certainly NOT considered "Abnormal"<quoted text>
Geniuses possess above average intelligence. A genius may be considered well below average, overall, as a person, depending on who you ask.
"Normal" is generally a range surrounding an average. There can be abnormal below average and abnormal above average. This applies to components that you can assign values to.
A person born with an abnormal below average sense of sight can develop an abnormal above average sense of hearing, for example.
All or most of the component parts of most human beings fall within the normal range. We decide what's in the normal range based on what we observe of most members of the species. We're all different though. There is no totally average person. Any one person may have several components very close to the averages. The other components will be further from average, even if still in the normal range.
When you are talking about the state of being of people, usually things those people can't readily change, it's extremely important to be careful with where and how you make value judgements.
I was certainly NOT making a VALUE judgement, as you said it was extremely important not to do this. A Genius is GIFTED with high intelligence , but could be very IGNORANT in "Common Sense".
You would be able to spot this by making conversation with a Genius.
