Naruto is also progressive in the sense that it's about breaking down traditions and putting into questions hierarchal systems of the past that led to and continue to breed conflict for future generations.

Notice how there's very little mingling of clans before Naruto, with blood purity and clan loyalty being more important than even the Village, and post Naruto, Unity between the big 5 is the bigger cause, with massive mingling of the bloodlines (half Uchihas, half Hyugas, no more Branch family shit).
