Regardless of how you and I may feel, the LGBT community is a very active minority that, through their energy, seem to overwhelm the mostly silent majority. Here in Omaha, BSA provides a safety net for a lot of boys from single-parent homes who might not otherwise have a positive adult male role-model in their lives.
My Son's BSA Troop already had to find a new sponsoring organization when BSA decided to accept gay scouts, as our long-time sponsor was a Lutheran Church (LC-MS) that is firmly anti-gay. I can't see how the decision to accept gay scouts and leaders into BSA will have a positive impact on membership, funding, and sponsoring organizations.
Time will tell.
