The entire issue of a "gifted" label also makes no sense to me, as in my estimation the strategy for raising a child should be the same regardless of what you might label them (of course, I don't think this applies to major issues such as autism spectrum, etc.).
There are real differences (some of which we know how to measure) in human cognitive abilities. You recognize that some kids have "major issues" which require different parenting and educational approaches. Maybe by analogy you can see that kids whose cognitive abilities are at the other extreme could also benefit from different strategies.
