I don’t see the connection either. But if I had to guess, he’s probably suggesting that, since Rand was an atheist who promoted acting out of self-interest...never mind, there was no reason to bring up the movie in this context.
I think the connection is fairly obvious. This female person (I refuse to call her a mother) was obviously in desperate need of help.
A true Objectivist would say society and its members have no obligation to try to help her and prevent what she eventually did, that in fact doing so would be counter-productive and in fact evil.
Or that at least forcing others to do so through taxation would be wrong. A debatable point, but in its full-bore form one that few can stomach.
