The school adminstrators recognize that it's illegal to refuse entry to the school based on the attitude of students about what sex they choose; so they came up with a clever plan:
Let them enter the school; but then turn them right around and walk them out the door based on what their parent's agree to before they apply.
Of course, they feel there'll be no need to explain to federal judges where they found this plan in the Bible, as just 'knowing' what God meant is enough proof of "our right to hold to the truths of God’s Word" Their holy judgement is enough to try to bully a sectarian government into submission.
The idea is to get rid of 'Pro-Choice' of parental choice in favor of church official's choice.
"The principal at St. John’s Lutheran School in Baraboo sent a letter to parents demanding they provide students’ birth certificates and sign an agreement that lists being LGBT as one of the “transgressions” a child can be expelled for.
Because the school receives federal funding for its lunch, transportation and No Child Left Behind programs, administrators can’t deny admission to students based on discrimination.
“If we cannot legally refuse students who are struggling with homosexuality or gender identification, we must maintain our right to hold to the truths of God’s Word,” Breitkreutz wrote in the letter obtained by the New Republic. “In other words, although we do not have the right to refuse admittance to people choosing an outwardly sinful lifestyle, we do maintain the right to discipline and dismiss students for these choices.”
