Bring them inside and explain why their beliefs are unfounded until they lose faith or are convinced I am Satan incarnate.

Depends on my mood and time: can be gentle, Often with amusement. Sometimes abrupt,

I had a friend he would see the Jehovah witness approaching his door, he answers the door in his underwear. Not sure this works for everyone. I would answer the door tell them about a few uncommonly known subjects. Like the earth and moon were equal in size until they collided and formed what we now call the earth and other unusual facts. They made it a point to walk on the other side of the street when they walked past my apartment .

Why would you not be civil? I have found them interesting to talk to, usually keep them longer than they wanted to stay.

I really can't stand them they'll force you into their religion

I politely school.them on the bible they are professing to know. Present them with questions they are unable to answer. Most will not return. I had one group of witnesses that would come every couple weeks they got to know my name. I enjoyed teaching them new things every few weeks about their religion lol.

Don't want you to waste your time. I'm just not interested. Shut the door.

I ignore them. I only answer my door if I have invited someone over.

I politely decline. I don't get into a conversation with any of them.

I invent a religion and tell them all about it. Usually they cannot wait to leave.

With door knockers, I tend to deal off the bottom of the deck.

Have you heard the good news? There is no God and we are the masters of our own destiny

Don't answer the door.

I ask them if they believe in reincarnation. They never do believe, and that usually stops them cold.

I am very civil to them at the beginning and engage them in conversation opposing religion, if they get to sassy I insist they leave. After a couple of visits the word spreads that its a waste of time to come knocking on my door. I am very proud that I had a great deal to do with a young married couple leaving the j-dubs and becoming atheists.

I would hand them a copy of The Hitchhikers Guide to the Galaxy and a towel, and wish them good day and good luck

I thank them for their dedication to their beliefs and tell them I respect them for the effort they are putting forth and ask them to respect me for my beliefs as well. I have often felt that the non religious could get better results with kindness. They already think we are stupid for our lack of belief, do we need to be thought of as a$$%^&es as well because we attack them? I try to stay calm and explain my opinion. I hope I plant a seed of doubt.

I am chuckling on this one as it brings back a memory of how I chose to deal with a very persistent group of door knockers. My boyfriend and I had just moved in together and we started getting door knockers right away. I tried being nice. I tried being cold. I tried being rude. Well, with one particular set of door knockers (JWs), they would not take "no" for an answer. They just kept coming back for more. One day I was cleaning and there was the knock at the door. I could see who it was through the window. Frustrated and not just a bit angry I went to the door and threw it open. They stood there with their mouths open. One turned away immediately, seeing that I was not clothed. The other young man stood there staring (not at my eyes) for a minute or so while I told them off and invited them not to return. They did indeed leave and never came back. Now, I do not share this suggesting you do this as it could land you in jail. Just sayin'....

If possible answer the door naked.

It amazes me that old ladies come to my door here where I live in south beach, FL. But they do. Half the time I am only half dressed when they knock so can't really let them in. But I always feel so sad for them so I always take their pamphlet and wish them a good day. It makes them feel so happy. So why not? Sometimes reading the pamphlet is quite fun -- entertaining! When I lived I lived in New Mexico, they always came in pairs. I was always impressed they found my house on a dirt road in the middle of the desert. How? The young one was always a bit nervous and in training. It was so cute! How could I not take their pamphlet?

Tell them you've been excommunicated from "the church".

Many of the door-knockers won't be allowed to talk to you...

[Additional win, they may report back to the mothership and the # of incidents will decrease]

If I have time, am not averse to having folks in for a chat, sharing tea/cocoa... Otherwise my standard response is that "My sis and I believe in something else". I haven't had occasion to state "what" that something else is... Coupe deville, flying spag. monstah, what have you... knockers have universally signed off with "have a nice day" or such.

Tell then to piss off

I have told well dressed, happy looking JW's who drove up to SOD OFF! And, I have let Mormon missionaries in for coffee (which they enjoyed) and danish cause they were rainy cold and miserable.

Well I have to share this joke first...Why are Jehovah's Witnesses all flat chested? You make a pushing out motion with your hand/arm as you say "Get off my porch" These days, because of my peep hole, I don't answer the door anymore. I've had the religion conversation for 40 years. It's a waste of time.
