You mean like family-only rooms in restaurants in saudi?

Isn't the whole idea of a public beach, as opposed to a private beach from which you can exclude whoever you choose, that everyone, including poor frustrated bachelors and single women, should be able to mingle and enjoy nature together?

If you don't like people ogling, then cover up! You can still enjoy the sun and sea wearing a full-body swimsuit. This 'burkini' just seems to be a variation on that.
