Blondie, quoting the WT: "This might offend or distract some ... [and] those who got a glimpse of such conduct might be stumbled."
We all remember how often the Don't Be Stumbling Others dictum was trotted out by the WTBTS whenever they wanted to control or eliminate a behavior they didn't like. And as much as it seemed like a good idea, it never really worked out that way.
Why not?
In one of his books (sorry, but I don't have the reference handy) Ray Franz observed that the inevitable end result of applying this indiscriminately is that the people with the weakest consciences—those that are the most easily offended—end up being the ones that determine the culture of a congregation.
So instead of having the more mature, balanced people setting the tone and standards of the group, it is set by the least mature and most unbalanced individuals.
Let's review: It's a cult!
