So the protests have no religious colouring? Like, it's not Shia vs Sunni vs Kurds vs Commies vs whatever, just a protest against poor government performance?

If so, it's a sign of good progress in Iraqi society and mindset. Such a thing wouldn't be possible just 10 years ago, it was always sort of 'us' vs 'them', these groups being ethnically and/or religiously defined.
