Christians who believe that they have a RIGHT to knock on others doors to "spread the word"?

If you have that right and it takes precedence over the rights of others to be left in peace to follow their own paths, doesn't that also mean I have the RIGHT to knock on your door and tell you about the ways of a witch or of Wicca? Would you like to be called to your door numerous times to be talked to by a witch? How many times a month would you put up with it? a week? a day? Would it set your teeth on edge to look out your window and see three or four people get out of their car and stand at your door knocking and knocking even after it is pretty obvious that you aren't gonna answer it?
