The "Who are Jehovah's Witnesses" tract with the two people on the front (which is still being distributed by the way) says it all.
The rules won't change and they are hemorrhaging their young members. I've discussed the silly rules before. In the 80s and 90s it was "to look like we were serious" as business people sometimes still dressed that way. These days the reason is "because we're different" and with that reasoning they will stand out like Amish in a decade or two while everyone else is wearing tight space suits.
