Whether they be Witnesses, Mormons, or another proselytizing religion, how do you deal with people coming to your door to spread their religion?
I just had my first experience since getting a place of my own and had a decent conversation through the crack in my door. After I told him I was an atheist he tried to use apologetics; when I told him I was familiar with his arguments and didn't find them convincing further explaining that I take a scientific route of belief and chose not to believe until there is evidence for a god. He understood and thanked me for explaining and listening to him and he left with a handshake. I was surprised at myself for how civil I was to him but how does everyone else usually respond?
I moved to the woods thinking the knockers wouldn't follow. Alas, two showed up.
I rolled my eyes and went back inside.
Haven't seen them since.
Honesty is just the beginning to understand and respect others differences. You handled that perfectly well. There is no reason the afraid or upset by anyone coming to spread the word they believe is putting them in a peaceful state. I actually find it very interesting to see others point of view. I had had a variety of people come to my door with their word and even witnesses and Mormons have their OWN point of view of their religion. Everyone should give everyone the opportunity to explain their peace, it's very mind opening.
I have have answered the door to various religious types sharpening one of my swords they usually get the point without me giving it to them.
Sectarians surprise us by often overstepping the bounds of decency that exist in our society. After all, if someone tells us that he is busy or simply does not want to communicate, we try not to impose our society on him. Sectarians are going ahead. Even when you directly tell them "no", it doesn't stop them. They are not aimed at dialogue and attention to the interlocutor, their goal is disputes. In order to protect yourself from them, install a stronger door with a good peephole so that you can immediately see that it is them. You can find more information about good doors using quality websites.
