Being rude is so unnecessary. Just say no thank you or don't answer the door. Jehovah's witnesses are not going to make you listen or burst in the house.
That' rude; I always invite them in to my home, for cookes & milk, but since, I live in the country, I don't get many of them, or any other visitors, for that matter!
They've yet to try but when the Mormons come by I usually answer the door with my ak in one hand wait for em to realize I'm holding it and then slowly close the door without saying a word I swear I made one pee himself once lolz.
