Kentucky (of all places) recently tried to get "ahead of the curve" by instituting a ban on child marriage. Unfortunately, this effort was squashed after opposition by a conservative group known as "Family Foundation of Kentucky".
And who are they? Well, let's just ask them!:
"Government has no obligation to ignore or deny, and has every right to acknowledge, that the United States was founded, primarily, by Christians, and that our laws and government are rooted in a Judeo-Christian worldview. Citizens, churches, private organizations, and public officials have every right to proclaim their faith in public settings and to bring their religiously-informed moral values to bear in election campaigns and public policy decisions." - Family Foundation
Looks like, if you are a member of this Christian group, you believe pedophilia is where other things were in the 70s....the 1570s, that is...
