At times in histroy the ruling classes have used marking or tatooing as a mark to notify the public of how to respond or be warned with regard to the individual bearing the mark.
In some cultures this marking practice has caused more problems than it solved. These individuals have banded together and gained influence among the populace, some for good purpose, some for bad.
I would like to think that our collective purpose is good. Our purpose should be educational, informing those who are in, and out, that this organization has lost God's approval if it ever had it at all.
Inorder to do that we must not shrink away from those who are in when we see them in public. Walk with your head held high and if you are happy then smile. Convey to them from your body language that what the Watchtower writes about us is incorrect.
So wear your mark proudly and if possible express it to them if they initiate conversation.
