Either way, whether one would consider it 'scientifically' accurate or just a colloquial term, it's not very polite or mature to end a conversation that way.
I mean, obviously you mean your child is very gifted, beyond what most people and even educators are used to dealing with. That's just a fact whether there's a good term for it or not. From my reading of the conversation, this person made it seem like she thinks if the term isn't used anymore, the folks for whom the term used to apply no longer exist. The subject can't even be broached.
That very high iq range was just all made up (?)
Sorry you had to be on the receiving end of that 5 year old level of behavior.
