Regarding those DNC signs on the door - we had in our teritory quite a few doors like that and I remember working with an elder who was so zealous that he would knock on these doors just to ask : "what is the reason you put that sign on? You know there are many untrue informations about witnesses so if you would like I can explain ...." and of course we would be yelled at and treatened with police.After one of those visits when we made householder very mad, next day he put up a sign : NO JEHOVAHS WITNESSES AND DON`T EVEN THINK OF ASKING WHY OR ELSE...GO BUG SOMEONE ELSE and than a very explicit swear word!
Sadly we taught he was in Satan`s world-mislead, and we are right-persecuted for righteousness sake.
