Why would the school even apologize? They are harmless quotes that 99% of the people would have never even realized where they came from if nobody said anything. So what if they quote Hitler, Stalin, Jesse Jackson or Clinton. WTF is the difference? We have a freedom of speech in this country and if people get offended piss on them. The ACLU and the liberals need to have such a perfectly "politically correct" society that people must refrain from even quoting a person now? It's B.S. What if they would have quoted Ghengas Khan or someone else who was maybe responsible for more deaths than Hitler? Would there have been an uproar?
