when i think back to when i was an active dub--late teens: pioneer; servant; public talks home and away etc---i tried to hide my religion from people i worked with and others who may have asked me. I was embarrassed and ashamed of it.
Now--i'm only too willing to talk about it if the occasion comes up..such as local public facebook groups. Its surprising how often the subject JW comes up in discussion groups.
No need to bad mouth the cult--just present the true facts as against the usual myths and misinformation.
