I, too, was brought up as a JW, so I cannot say that they "changed" my view of anything.
In the prior thread concerning the ethics of JW's, at one time I would have said that they are the most ethical people on earth. However, from experiences that I had and things that I saw as time went on, that view was badly shaken.
"Ethics" were for those who could not figure out how to manipulate the rules. In the congregation I attended most of my life, ethical principles were tightly tied in to one's position in the congregation or one's associates.
There was the pioneer sister who had multiple DWI arrests on her record, and several citations for hit-and-run accidents while she was intoxicated. She was also well known for her lewd conduct towards unbelieving mates of sisters in the congregation. She was liked by several of the elders, however, and because of that, there were never any repercussions for her.
There were also several sisters who were encouraged to go on welfare so that they could spend more time in service doing "God's work". They were perfectly capable of supporting themselves and their children....and, in fact, were doing just that....before they came into the "truth". They were advised by others in the congregation that they should accept government money in order to spend more time in service. These sisters promptly quit their jobs and went on the dole. After doing so, they spent most of their time gossipping about others and spent very little time in service.
Then there were the sisters....one a chiropractor and others who were her patients......who were caught in numerous acts of welfare fraud.
I could list many other examples from this one congregation alone showing that JW's are no more nor less ethical than any other group of people.
I DID find, however, after becoming inactive that the "world" was NOT an evil cesspool with greedy, hateful people running rampant. Most of the people with whom I have been associated are at LEAST as ethical as JW's, if not more so. Additionally, they act in an ethical manner because it is what they feel is right, not because some elder might find out and they would be counseled about their conduct.
