I was just going to mention something about that in the market researchers thread because I lump marketers (not necessarily researchers) in with the JW's and Mormon missionaries who come to my door. What makes the situation worse for me, is that I have been baptized Mormon, although I am no longer "active", and haven't been for twenty years, and have no intention of ever "re-activating". However, since I am on their books so to speak, I get phone calls and house calls from missionaries and home teachers three or four times a year, until I get rude enough with whoever it is, so they realize I don't want them around. By the way, I just got one last night, a home teacher, who happens to be a lawyer in downtown Calgary. I have been contemplating calling his office to retain a lawyer to get a restraining order against a church that has been harassing me.
As for Witnesses, the last time I had one come to my door, I was living in a cul-de-sac, and a full size van pulls up, loaded. The people in the van stayed there for a minute or two, then exploded out of the van in pairs, heading for different doors. I knew immediately it was an invasion, so I opened the front door, and left the screen door closed. I then instructed our rather large dog to lie down just behind the screen door. When the knock came on the screen door, the half asleep dog came up startled and full of teeth and *******. I did feel bad, (and later very angry) because the pair that came to my door was an approximately 10 year old boy, and his grandpa standing bravely behind the boy. The boy was highsticking bricks and holding out a quivering hand with a pamphlet, and stammering throught the beginning of his speech as the dog sized him up. The grandpa, seeing the kid struggle, was pushing the kid closer, and forcing him to proceed. I have never wanted to say "SICK 'EM" more than any other time in my life. I told them that I knew who they were, and I was not interested. You should have seen the look of relief on that poor kid.
As for something to say to Witnesses, try this:
"Do you really believe the world is going to end soon?"
"Well yes, it says right here in the..."
"Wanna sell me your car for a buck? You're not going to need it."
