If the author's point was to demonstrate that it's a big mistake to be emotional/angry when addressing important issues with children, I could agree.

Unfortunately, the author seems rather proud of it. That her outrage on the subject is more important than effective dialogue with her kids. Reading between the lines, it seems certain that that would extend beyond this one incident.

And, hearing of a (presumably decent) boy badgered about raping his unknown future-wife is infuriating. Further, later on he actually had to explain why he was angry. There is way too much of this garbage drowning out real discussion on this issue and it needs to be called out (as illustrated by the nearly unanimous approval here in the comments).
