On our nationally ranked swim team, the fastest kids go first. End of story. My son at one point was faster than some of the kids but was too shy to push ahead. We mentioned it to the coach, and he finally encouraged him to go first. There was no bullying; it was simply who was the fastest.
We are heavily involved in Cub Scouts and have never heard anything about gays in Scouting. We are in a pretty liberal area though. I have thought the reason why they don't want gay leaders is b/c they somehow think that gays would be more likely to molest little boys than straight leaders (which I don't think is true). There is also a very heavy Mormon influence in Scouting. However, that would to my eye not be bullying either but simple prejudice (which I obviously don't agree with).
