An interesting thought peacefulpete and perhaps you are generally right. I feel this way because while it is true that we are a older religion (in regards to age demographics) the type of person in the congregation are quite different to those of the recent past.
In the past, Witnesses lived more by principles where they took pride in taking the moral high ground. And actually were happy to suffer because of it. When these ones were disfellowshiped most (while not enjoying the process) accepted their mistakes and the consequences.
Today though I see most Witnesses as a whole lot weaker morally. Not that they are more immoral (say about sex) but less directed by personal conscience. In stead our people today are more like spiritual jellyfish that float on the current coming from the Governing Body. And so have no real problem with the beard or pants thing ... or anything else that appears in the future. Yes, some might become a bit perplexed, but not bitter.
Its a bit like kids who used to get told to do their school homework every night, and then realize that they don't have to do it during the holidays. Are they 'bummed' that they had to do it in the past? No. They are just happy that they don't have to do it now.
Those on the outside, might have a different view of things though.
