You can HAVE religion classes, you just can't TEACH religion

"The university's rules aren't affecting a lot of students right now because they apply only if a high school submits new courses to the university for approval. But it is easy to imagine, at some point, university officials reviewing the 150 or so religious schools whose current classes would be regarded as unacceptable if new. 'If California prevails,' Mr. Carney says, 'the only way for students to go from our schools to university would be to strip out the religious elements of their education.'

Indeed, a list of 'helpful hints' from the university -- offered to high schools as part of the curricular review process -- suggests stripping religion even out of the religion classes: 'Religion and ethics courses are acceptable...as long as they do not include
among its [sic] primary goals the personal religious growth of the student.'"
