Hope certainly wouldn't know that "Gifted" is a common term used by magnet schools and accelerated programs, but I suspect the writer may not have known either.

(haha, magnet schools. eric should make a joke about that at some point).

Although, to the wider point, I think that Hope might understand Magneto a little better. He has been historically proven more right than Xavier. Their greatest problem hasn't been prejudice (in the legal issues, economic discrimination, bullying sense) but extermination (Sentinels, Registration, Reavers, Ulti-Men, Operation Zero Tolerance, Friends of Humanity). Xavier addressed the first with a problematic approach (from Hope's Askani perspective), but didn't deal with the second in any organized way.

Magneto focused on extermination, and did many questionable things to prepare for the war he knew was coming. Genosha, for all its flaws, is an understandable and successful play. The disaster destroyed it, but it probably would have been worse if they hadn't gathered. The sentinels were destroyed before they could threaten other mutants world-wide. scattered, Cassandra Nova might have been able to kill all mutants. I think Hope can appreciate that kind of sacrifice, even if she's unlikely to go to Magneto for moral guidance, at least she can count on him tactically. Xavier isn't so clear a resource.
