I can't agree that this is a backwards step, or anything like it.
Anything that moves us in the direction of providing children with same-sex attraction the ability to navigate their youth with an increased sense of normalcy and/or belonging is a huge, positive step in helping them to develop the reserves of self-respect and inner strength that they need to become healthy, whole adults.
It is disappointing that the BSA stopped short of allowing participation by Gay adults, but this is a pretty hot-button issue, and it is hardly surprising that they punted.
Rather than cause a tidal-wave of suicides among Eagle Scouts--a notoriously resilient crowd--I expect it will cause a tidal wave of law-suits by gay Eagle Scouts, demanding the BSA explain in court how the clock striking midnight on their 18th birthday transformed them from the most valuable, highly-respected and successful members of the organization into Pariahs.
By the time these lawsuits occur, the BSA community will--one hopes--have discovered that having gayz in the family is nothing to be feared, and they will abolish this arbitrary and utterly illogical cut-off.
