Sounds more like you attacked them, and they defended themselves. I can't tell where you stand. Are you saying you didn't want to be reminded of the war while you were on board? You sound very passionate about you're feelings. How about the televisions in the airport showing the war. Did you return your airline tickets? The war is being reported everywhere 24/7. If you don't like it, stay home, shut off you're tv, radio, telephone, cancel the newspapers, stay off the internet and don't talk to anyone. Perhaps that will make you safe and secure.
I don't think you showed Princess anything. Perhaps you weren't ready to cruise. You ruined it for yourself. John Lennon's song is a message of peace. I find it shocking that it made you so hostile.
