I wouldn't say I would ever 'dread a Witness coming toward me' I haven't been disfellowshipped and I hadn't done anything to feel ashamed of.
I felt comfortable talking to witnesses, even the elders who came to my door however it would change when they brought up the subject of the 'truth' and I had to defend my position. There were some subjects they found were a sore spot, unfortunately. Some teachings have affected my life detrimentally I believe. 1975, the generation teaching. This has also affected the next generation in my family. I feel the need to explain why they were so bad and how they have made my/our lives more difficult by listening and having faith, demonstrated by how we adapted our lives to what we believed were things coming from Jehovah.
