I'm sure everyone remembers the controversy in Nevada a few years ago. Brittany McComb, valedictorian, decided to use her opportunity at the school's graduation ceremony to evangelize, despite the school already warning her the speech was not appropriate. Here's the youtube as a reminder:
Of course the extreme right wing cried foul & made up silly arguments, claiming her free speech rights were violated, etc.
After the school board pulled the plug on her evangelism on the school board's dime, the young lady sued. She lost. Now, she lost the appeal. (See the pdf of the ruling.)
Judge Kozinski, citing previous 9th Circuit law, said the young lady was not denied her free speech rights at all.
[School officials] did not violate McComb’s free speech and free exercise rights by preventing her from making a proselytizing graduation speech. Nor did they violate McComb’s right to equal protection; they did not allow other graduation speakers to proselytize.
It is unfortunate that some well meaning believers cannot stand not having the government give them special treatment. No other faith is allowed to evangelize, nor should be, on the government's dime. No other faith is allowed to hold a captive audience of spectators at a graduation. Nor should the price of admission to witness a high school graduation be an evangelistic effort or prayer meeting.
Freedom for all means exactly that. It does not mean one group gets preferential treatment.
