Actually, considering that she talks to the women, and they end up deciding not to go home with the man, she's probably on to something. It's not like the women she approaches can't tell her where to stick it.
That something, however, is not that women are weak - it's that there are weak people, and they are preyed upon, and what she is doing might help one or two of them.
As a side note: Yes, I think she's kind of sad, myself. The idea that aloneness is superior to togetherness is rather depressing to me... but also keep in mind that this is ABC news, and if it's not out of context, it's not news. I'm just glad that she's found a reasonably harmless, and possibly beneficial, way to cope with her own feelings of helplessness.
