BSA can do what it wants, if I have one boy bullying or sexually harassing another boy, he's out of the troop. That's been my policy long before the homosexual issue was politically correct. I was a CA for 15 years and I didn't tolerate any bullying or sexual harassment from anyone whether they were homosexual or heterosexual.
BSA has it's policies, I have mine. If anyone in my units does not feel safe and comfortable, the reason for that discomfort or danger is removed, no second chances. As long as the youth know that up front, there shouldn't be a problem. I have held that standard for the past 45 years working with youth and never had the experience of removing a participant from any of the programs I have worked with.
