The Hallelujah Effect is when an audience shallowly interprets a piece of media that uses political or religious themes in part to discuss sexuality, ignoring the sex in favor of the political or religious themes.
The Second-Order Hallelujah Effect is when an audience is overly conscious that the political and religious themes in a work are "secretly" about sexuality, and believes that any on-the-face interpretation of those political or religious themes is moot or naive.
