How many of you were Boy Scouts?
I was Order of the Arrow and a Scout for many years. I can honestly say I never once discussed sex with my scout master, or ever saw him having sex with his partner of choice (his wife I assume).
I did however sit around the campfire with my buds talking for hours about the girls in school that gave us the chubby fits.
And as long as the BSA takes federal money of any kind they are subject to antidiscrimination laws.
A person's sexual orientation has no bearing on his or her ability to teach the skills in scouting.
From Memory:
A Scout is
Trustworthy, loyal, helpful, friendly, courteous, kind, obedient, cheerful, thrifty, brave, clean and reverent.
Don't see anything a gay scoutmaster can't teach.
