Well, I would say that the JWs that bullied me into deciding they weren't Jesus' true disciples have as much "responsibility" for killing my faith as I would have if I actively tried to dissuade a JW from their belief.
While I don't actively try to dissuade JWs or anyone else from what they want to believe as The Truth™, I won't tolerate anyone trying to re-indoctrinate me or using religious seduction techniques on my children.
