"Do they use Greek Mythology as part of school work or assignments? If so, I smell a double standard that may need exploration."
The difference is this: greek mythology is studied for what it is, namely, mythology. How would you feel if kids learned about "Christian mythology" in school? Christianity is too sensitive a subject to study honestly; hence, state-sponsored discussion is banned.
Remember that separation of church & state protects both citizens and religious organizations' integrity. Greek mythology is not a religion in any meaningful way, because nobody takes it literally. It is, however, a revealing and fascinating study of human emotional archetypes, and critical to understand as the jumping-off point for many great thinkers, both Christian (e.g., Aquinas) and secular (Camus).
