I keep labels in my purse that say "example of cult propaganda" and slap one on the covers of mags I find at public places.
I also use labels that say " WARNING, the watchtower society silences victims of child abuse, read at your own risk"
I also have printed out wanted posters for Fred Mclean, a JW who is one of the US marshalls 15 most wanted fugitives. He is a serial child molester that the societry freely allowed to move from congo to congo molesting dozens of children. I like to slip one of those posters inside the mags too.
Just little things that make me feel good inside.
