If this had happened at the FLDS compound in Texas, do you think the suspect would still be awaiting arrest? When Texas authorities received an anonymous tip about a (fictitious, as it turned out) child bride who had been married against her will and abused by her husband, they swept in and removed 439 children from their families and warehoused them until the courts ordered them returned to their parents.
Sadly, the Grant County case is not a freak occurrence in the Amish community. It's not even the only one in the Midwest this year. Amish children are especially vulnerable, since the faithful are taught to shun the outside world and avoid the secular authorities. They also believe in forgiveness rather than prosecution.
But, by and large, Americans hold the Amish in high esteem, so we give them the benefit of the doubt. Just as faithful Catholics give their church the benefit of the doubt when bishops protect abusers rather than their victims. Have any Catholic schools been shut down in the wake of those abuse scandals? I haven't heard of any.
But if a religious group is not only in the minority, but also widely despised, a whole different set of rules apply.
