....keep myself physically strong, mentally awake and morally straight.
I don't think they envisioned "straight" being translated as it applies to homosexuality but its pretty much intended that way in the broader picture.
However I don't believe a homosexual is any more likely to victimize a scout as a heterosexual would - unless they are Catholic priests or Penn St football coaches.
Therein lies the problem.
You might have felt a lot safer letting your son hang out with Jerry Sandusky because he was "married, had kids, a family man, etc," than letting them hang out with a homosexual person.
Which would have been wrong?
