I do not really see what the Heck the big deal is.
Sweet Heart of XYZ is showing they are ladies who feel XYZ and the members are special. They are not pronouncing them selves as members are they?
Same things go for Moms or Dads. LOL!
PNM wearing letters show who they are affiliated with, wearing the Coat of Arms is a no, no.
This is a form of Advertising for that GLO!
Goodness, the popcycle unstuck from an oraface!
If Your GLO has rules then do not do it. If it is not spelled out ask!
The problem today is not enough GLOs are proud enough to let others know their affiliation by wearing letters, C of A, or Pins!

Is that saying you are not PROUD of Your GLO?
