As I said, you needn't overkill loli fanservice to have a good loli show, if the characters and their characteristics are good by themselves. I like a good lolioverkill like Moetan or Ryufuko, but it is not just being pedo for the loli as much as it is being pedo for the archetype, I would say.
Needs fucking research, but no one seems to be willing to study the taboo. Psychology researchers can't just tell the world "lol, actually u guys are wrong" because if the truth causes a kind of societal cognitive dissonance, any theories are simply dismissed by society. Some claim that Freud deliberately skewed his research "results" to conclude something that society would be more favorable of and willing to accept. If society just points back and says "NOU" when they learn something they don't want to hear, the nice boat is never leaving the harbor, so to speak.
