I agree with what he has to say, Searril. I have had experiences myself in regard to jws. I had people at work who knew I was or had been a jw, ask me why they were getting a letter from a total stranger and commenting on their relative's death. Or a letter out of the blue. It is not this man looking for something to bitch. He had several different instances and was saying what passed through his mind and how it did not lead him to God.
I got a letter myself from a sister in the same town I lived in who I knew although she was in another congregation. She did not recognize my name or me as a jw.
It is a surprise for many jws that people find these behaviors strange. Reverse the circumstances, imagine you're getting a letter from a complete stranger, obviously more concerned about their religious message than how you are experiencing terrible sadness and loss. Or how creepy to get a letter from a Mormon telling you they have the bible answer to your situation.
So don't attribute bad motives to this person. He is just giving his experience to these things.
