The articles from the UC Davis blog and the Family Research Institute you've quoted are review articles rather than primary research articles, which means there's a lot more opinion in them than there is basic fact. But they both show pretty well that while there is controversy, nobody's research has provent that homosexual adult males are more likely to molest boys than heterosexual adult males.
The key point to focus on is this, gentlemen and ladies: if you want to protect your kid(s) from pedophiles, you have to be involved in their lives and activities. You need to meet their coaches and other adult mentors, look them in the eye, and make sure your spidey-sense isn't tingling... if it is, you need to be really vigilant. Teach your kids what to watch out for so they're less likely to become prey to a pedophile.
You can't legislate your kids safe, either in society, or in the BSA.
