I teach worldviews classes to high schoolers. We cover Secularism, Postmodernism, Islam, New Spirituality, Christianity and Marxism

Not to nitpick, but Islam, New Spirituality, Christianity are not serious worldviews, they are at best worldview wannabes, IMO nothing more then any other monotheistic religions where God used his magic and puffed the world into existance.

Once Upon The Time is not a worldview.

From Wikipedia:

Secularism is the principle of the separation of government institutions and persons mandated to represent the state from religious institutions and religious dignitaries.

So, Secularism is not a worldview.

Postmodernism is a 20th-century movement in the arts, it could be a worldview when one is on mescaline, but that's a subject for other occasion

Spot on with Marxism, it is a worldview, so if you are into worldviews you should just teach that
