Right on, rebel8. This was my last encounter.
"You are Jehovah's Witnesses, right?"
"Yes."
"You are not welcome here. DON'T come back." *shuts door*
Then, I called the KH and left a msg. with my address and requested a DNC note on the territory card. They didn't come back.
If I decide to confront or have any discourse with them, it will be at their KH or trolley. My home is my sanctuary, no JWS allowed.
