Labeled "Dumb"

Is it fair that stylelist is labeling these girls dumb? 

Reasons:

 One wears a "balance bracelet" [British national treasure, Kate Middleton.

 The other raves about a detox diet [uhm-hm, Naomi]

 all while the third claims to eat chemical-free food [Gisele]

I really don't care if what they are doing makes is dumb or not; however, my question is... are they being labeled dumb because they really are or because society has the need to criticize them?
