You are the one making a value judgement here.
Practicality is another matter.
You can make all sorts of ‘feel good’ statements about ‘different intelligence’ all you want. Fact of the matter is, if someone is only capable of working on an assembly line or being an order taker at a fast food restaurant, and that job has been automated out of existence, what do you propose we do with those people?
You have HAD your explanation, in full. I guess your I.Q. isn't capable of hearing anything else but the song YOU sing. YOU are the problem, not the rest of humanity, high OR low I.Q.
Poor Agnes, you are doomed to a life of frustration.
Seek the Lord! I hope you find peace. You sure won't find YOUR brand of perfection...especially in your own mirror, but you will find peace in the Lord.
