My apologies, I lose myself sometimes...
What I mean is that I feel that the extreme example of the "us vs. them" mentality is detrimental to coexistence. To agree with you, I appreciate the differences between people/cultures/opinions, etc.
But when this "us" becomes unconditionally correct in its actions, when so many of this country's citizens accept and back its government's actions because of a blindly nationalistic mindset, something's wrong.
I'm not saying that it's new or limited to this country, it's most countries of course, but that's what I mean when I talk of turning a war into a football game. It ends up about rooting for your country, your team, merely because it's involved in a conflict with "them". The objectivity disappears.
