@OP - in the past MOC has given large presentations at Bass Pro on OC while the speaker and many in the audience were OCing. So unless something has changed recently, I think you got bad info on BP. The only issues ever noted at GLX mall was with one particular OCer (who is the only person ever in recorded history to be barred for life from becoming a MOC member) and he has since faded into the woodwork, so again, I think you are getting bad info.
Kind regards - G9OS
