I am decidedly not non-confrontational. I just fail to care about helping a current cultist who believes it strongly enough to engage in recruitment.
Mainly, it's because I know the help-one-person-at-a-time approach is SO much less effective than prevention efforts.
I suppose I am helping the individual a little bit by having a firm answer instead of just not answering the door or saying, "No thank you." She certainly knows I object to her message, at least.
Also, it was in the middle of my workday.
