At Bastrop High School in Louisiana, on May 20th, the graduating class, led by Laci Rae Mattice, went ahead with their traditional prayer despite ACLU's saber-rattling on behalf of one atheist student. You can read the account here, I hope this young lady considers a career in politics; Lord knows we need representatives with Christian conviction and courage.
As for the young atheist, I hope he learned a valuable lesson: that he cannot force upon his fellows his atheism. If it took until his graduation day to learn it, so be it. Let us pray that he comes to repentance and conversion.
