I understand passing your own house, not answering the door, telling them off, etc..... when you ask them repeatedly to not come back, you write NY and tell them to put you on a 'do not call' list you may be afraid of what you will do TO them not afraid of their message or them personally. They simply do not understand they do not have the right to come to my door unannounced, it is rude.
I know many people who have tried being polite and saying not interested but jw's don't give a crap, they care more about getting their time in. People just don't feel like dealing with the nutjobs and why should they? it is THEIR property they get to make the rules not the jw's who get annoyed because they hear people inside.
The best story I heard locally was a guy was having a little quality time with his wife Sat morn and the jw's come an interrupt, they did not answer hoping they would go away. Could the jw's respect their privacy? no, they peeked in windows and kept knocking. So the guy answers the door buck naked and what does the jw have to say? tells the guy to put some clothes on! He answers, "why should I? it is my house and you are the one annoying me after knocking and knocking interrupting my love making." They had a few words but needless to say that guy was in no mood to listen to the jw's gloom and doom message.
don't jw's know the saying 'ignore them, maybe they will go away' ?
Personally I wish there were no knock laws everywhere. The jw's who look in windows should be charged as a peeping toms.
