The noisy and obscurantist parents who figure in your article might have joined her class in order to learn that 'a clear moral framework' incudes clean and unambiguous information.
The morality is provided by the pupils. For some of them 'a stable married life' may become their moral choice. For others, it may be enough to decide: 'condoms are morals'. But the value of untendentious teaching is that it does not limit the range of moral choices that can be based on it.
