And, for your reading enjoyment, a recent case involving the ACLU:
Thanks to support from the American Civil Liberties Union,
Stevenson High School in Sterling Heights, Mich., has been forced to
back down after it censored Class of 2001 Valedictorian Abby Moler.
School officials removed a biblical quotation from a statement Moler
made in the class yearbook, telling her she wasn't allowed to make
religious comments. The school will issue a written apology to Moler,
add her quote in file copies of the yearbook, and will "train its staff
on free speech and religious-freedom issues."
