The questions your asking about the morality of a football chant inevitably lead to one side saying, "Grumblegrumblegrumble." And the other raising their cheap, red plastic cups and shouting "WOOOOOOOOOOOOO!!!"
1. Guess who is having more fun.
2. Guess who lives in the real world/modern era.
3. Guess who's voice is louder? (Intended as humor, not a vindication of the following.)
4. Your basing your morality on what exactly? Because I doubt you can logically prove your system of ethics is superior to mine. In fact, civilizations have been attempting this for thousands of years. All of them have failed before the almighty individual in the end. You will fall as well. I suggest you leave others to their own devices. It's the only way to not come off like a total DB. Because no one likes being told what to do. Especially when they pretentiously claim the moral high ground.
