I find it entirely appropriate that recruiting managers wear their biases on their sleeves, in this manner.
As representatives of the organization, you put its core values and culture at the forefront. You represent what the owners are really all about.
It is important for those with the ability and inclination to be part of "an association for superior IQ people" to not be placed in an unsuitable role, at an unsuitable company, given their rarity. Better for all involved, I would say.
