Texas ? The state of Texas made a damning accusation when it rounded up 462 children at a polygamous sect’s ranch: The adults are forcing teenage girls into marriage and sex, creating a culture so poisonous that none should be allowed to keep their children.

But the broad sweep – from nursing infants to teenagers – is raising constitutional questions, even in a state where authorities have wide latitude for taking a family’s children.

The move has the appearance of “a class-action child removal,” said Jessica Dixon, director of the child advocacy center at Southern Methodist University’s law school in Dallas.

“I’ve never heard of anything like that,” she said.

Rod Parker, a spokesman for the Fundamentalist Church of Jesus Christ of Latter Day Saints, contends that the state has essentially said, “If you’re a member of this religious group, then you’re not allowed to have children.”

Attorneys for the families and civil-liberties groups also are crying foul. They say the state should not have taken children away from all church members living at the Yearning For Zion Ranch in Eldorado.
