This point needs to get more attention, anyone who is boiling this down to a simple black/white situation is oversimplifying the issue.

Determining the value in integrating "gifted" kids with "non-gifted" kids is in effect the same argument that is held with regard to determining the affect that charter schools have on our school system, simply change the modifier from gifted/non-gifted to interested/uninterested in school and we are having the same debate.

There are pros and cons to both models and people have to admit to both sides of it, otherwise they are being disingenuous with their analysis.
