What do you typically do when Jehovahs Witnesses come to your door?

Actually i usually just answer the door and once i learn their purpose i in advance let them know that i have views that conflict with theirs. Only two sets have cut and run, the others will at least hear my view and give their own in a mild debate and they come back to talk later. Personally, i sort of believe that many people would be more willing to discuss views without attempted conversion if they were not so worried about what their fellow followers would think about their willingness to listen and debate!
