I belong to several work related groups on the internet that help me network across industries. I currently work in both the encrypted communications field for a fortune 500 company and I have a small side business with my wife in private investigation / security. The problem is that any coworkers from either field can see me profile and I know my boss and many coworkers for my full time job are members of some of these groups. I dont know that any of these people are anti gun, but you never know. My gut feeling says don't mention the firearms competition (IDPA), but at the same time many people are also into firearms who may want to network. I dont know how publicly accepted firearms competition is compared to the more controversial firearms topics like defensive use, etc. Im planning on erring on the side of caution and not saying anything, but I was wondering what you would do in the same situation?
