I for one believe the uniform should be... well, uniform. If one is going to do it have everyone do it.
Our association distributed 2.5"x3" flags to be worn on the left sleeve. BTW flag etiquette dictates stars forward, which is why these particular patches are to be worn on the left. This decision to display the flag as part of the uniform has been met with approval by most and apathy by some, but to my knowledge there has been little if any negative response.
