I am conservative and I oppose what she did. No parental pre-approval was given here. Any talk related to sexuality should have preapproval.
This was a Catholic high school and the talk was part of a series billed as talks on JPII’s Theology of the Body, about marriage and sexuality. Everybody knew perfectly well what it was about, and in fact, one of the sections is on social attitudes and Catholic teaching, which is exactly what she was discussing.
