Inconsistency is not necessarily hypocrisy.
The differences in Cub neckerchiefs are by program, not by den as such.
The BSA rule on neckerchiefs is largely ignored, like wearing denims with the blue Cub shirt. Because most troops are not Patrol Method troops, there is little pressure for formally allowing patrol neckerchiefs. Troop. Troop. Troop.
I think patrol neckerchiefs are a great idea, like large, square neckerchiefs and going back to registering patrols as "units." So long as it has no financial impact, BSA would like those ideas too.
