experience has taught me the following:
....." of course I love Jehovah and consider myself a witness ....I am going through a low spiritual time"; that will get them off your back..
I have learned from personal experience that
you will not win any confrontations-so do not waste your time. Tell them what they want to hear and plan a slow exit. Keep your distance from them and always "have other plans" if they try to schedule a meeting with you. If they come to your door unnannounced simple say " bad time" and close the door.
It worked for me until they decided to come after me with Judicial meetings about "drugs" and "fornication" ( totally fabricated). So I hired a lawyer and began a harrassment suit (not against Watchtower; against the elders personally). They backed off fast. I suppose I followed President Teddy Roosevelts advice to " talk softly and carry a big stick".
