I would order an info packet/DVD from the whole network & have it in hand when you bring it up. Leave her w/ info to read!
I haven’t seen the actual materials provided by thewholenetwork, but I prefer speaking from my own understanding, which come might across as more genuine than simply handing over some sort of media. I would fear being perceived as pedantic, which is pretty much my central concern when it comes to inter-personal intactivism.
That said, I can imagine that some people may feel intimidated by the challenge of advocating intactness, and I’ve given a few copies of Cut to a couple of friends/family because I felt it was an entertaining and thought-provoking film.
