There's not much about the JWs that's the same as when my grandparents took it up in the 1930s or when my parents were indoctrinated into it. Even in my time it's changed a lot. I think my mother still practices a quasi-1960s version of it. They just redefine stuff to suit the needs of the day.
I'm sure they used to wear pins and badges in the early days? Or am I imagining that?
