Just wait and see, eventually it's going to be against the law to be a Christian in the USA, against the law to wear a cross, against the law to attend worship services, yet the promotion of immoral lifestyles, murder, rape, theft etc are being broadcast every day on TV and radio.
Obviously the school board needs better legal advice, if they took out only the bricks mentioning Jesus under threat of being sued, and left other religious or church-related bricks.
