It does sound rhetorical. A more 'honest' approach would be "Is it because it is more socially acceptable for one sex to lead single lives, not so much for the other?"

I don't really see why you'd assume that women are more frowned upon in this situation. I mean, there's even a picture of SUPERWOMAN in this article! And yet, your initial position was to think that women were the 'victims' here. (For lack of a better word.) Interesting, isn't it?

If anything, single women are shown as courageous and going against the tides. If a man decides to lead a single live, he is not seen as a hero. At best it's inconsequential, at worse he's a loser.

And this tendency of inconsequential/loser for the men applies to many situations.
