I don't remember whether the WCG made an issue of standing for the anthem...I do remember that I did stand, whether it was because I personally thought it was ok, or because official doctrine said it was ok, I just can't recall anymore. I seem to have a vague memory of "standing only shows respect, not worship' or something like that, but again, that could have been my own thoughts.
What I do remember is being sent to the principal's office on several different occasions for refusing to say the pledge of allegiance. Ironically, I also remember saying "I affirm" instead of "I swear" during the court sessions I was involved in, AFTER I was already DFed from the WCG, just like I had been taught. The irony being that I was DFed BECAUSE of being in court, and testifying against my parents when the state and social services removed me from home and placed me in the foster care system.
