You make an excellent point about the new rule already being </i> de facto</i>. I saw a picture of 1 scout in uniform at Grapevine during the business meeting who was said to be a self-identified homosexual. In my readings, I have only come across 2 instances where a self-outed youth scout was kicked out of BSA - 1 in 2000 in the Old Hickory Council (NC) and the other in 2012 in the Silverado Mt. Diablo Council (CA). Undoubtedly there have been others, but my impression is that it is a rare event. Unquestionably, sympathetic troops have shielded known homosexual scouts over the years. The recent rash of scouts being expunged from the BSA have in reality been scouters, i.e., older than 18 (early to mid-20s). Many of these men were employed at summer camps. But you are so right, what volunteer would want to expend the energy in attempting to expunge a self-outed scout now when the likely result would be tremendous blowback on him by the homosexual lobby.
But, of course, the pro-resolution officials knew that the new policy would de facto in effect immediately. The long "implementation" period will be used by homo-fascists to inundate top officials with demands to design the new queerified BSA into their own image, and the top officials will, of course, cave.
But, as you stated, a lot can happen through the rest of the year. Hopefully, the organization will completely implode through the massive exit of money and members. This is really our only hope.
