Bingo! There are no "lone ranger" scout troops; there will always be interaction with other units in inter- and intra-council camping events, competitions, and shared scouting facilities. There are also subject-specific "camps" emphasizing certain aspects of scouting that comprise members of many different troops. One of my biggest griefs in this respect is the fate of the Order of the Arrow, a sub-organization that is a perfect example of interaction on a nation level of scout members.
One horrible result I'm expecting is the formation of all-"gay" scout troops, most likely being sponsored by the most radical mainline churches like the ECA and PC-USA. These troops will write their own rules - never mind the meaningless "standards" of non-sexuality promulgated by national. The national org has already turned a blind eye to scouts marching, in uniform, in a "gay pride" parade in Utah - it will only get exponentially worst and in-your-face.
These all-"gay" scouting troops most certainly WILL attend multi-unit scouting events. They will be absolute poison to all they touch.
If the Anglican Church could proudly parade their gay peacock bishop it is not impossible to imagine that the liberal churches would just love to show the nation how “enlightened” they are by having gay scout troups. They would be competing with each other to be the first to welcome the gay/bisexual/transgender scouts. Tolerance is the greatest virtue of the day.
