Exactly. That's how it is explained in the book SO FAR. Theres more to Athena's hatred than her obvious resentment of her role in Rome. Poseidon got hated and feared as well. He didn't change as much as Athena, but Romans never had strong navy because they feared Poseidon. And Mars became more respected then both him and Pluto. Archery in Rome wasn't popular, which I doubt pleased Artemis. But only Athena got pissed. And it is said that whenever an opportunity for union of 2 camps appeared, children of Athena would cause another war. Whenever campers from Jupiter and Half Blood met, Athena's children are those who would start a fight. Why? It's obvious that it's not other campers who are messing with their paren'ts minds. It's Athena, messing up with minds of her own children.
