Maybe I’ve been sleeping under a rock recently, but I didn’t realize that half the metro Denver area was abuzz with a proposed sex education curriculum for its public schools.

As I looked at various media accounts, only one religious group — Catholics — stood out as opposing the substantial changes in how Colorado kids would learn about sex. There’s no mention of organized resistance from other groups, even the evangelical behemoth, Focus on the Family, an hour south of Denver.

Here’s the big question: How far into the story do readers need to dig to find out the crucial question here is parental rights, in terms of having the ability to opt out of classes that violate their religious convictions?

If it passes the General Assembly, the bill would amend a 2013 law by removing a waiver for public charter schools that lets them pick other sex ed criteria. It would also fund a grant program for schools that lack the resources to teach human sexuality and expand upon the LGBT relationship portion of the curriculum requirements.

The new section on teaching about “healthy relationships” and the “different relationship models” students may encounter appeared to be the touchstone for most of the objections from parents, educators and faith leaders Wednesday. Dozens of speakers told the committee they worry that if the General Assembly passes the bill, school districts will be teaching kids about sexual acts and lifestyles their faith disagrees with.

“If you’re for House Bill 1032, then you’re for exposing 9-year-olds to sexually explicit techniques,” said James Rea, a father of four. “We don’t want to expose our children to this kind of forced sexual education.”

Who are the “faith leaders” involved? One, according to CruxNow, is the Catholic archbishop of Denver. Crux said:
