Female only cities... How does Saudi Arabia expect this to help at all? This sounds an awful lot like what the Gestapo did to the semitic population in WWII. I don't think will achieve much to anything.
With the only difference that these female-only cities were proposed by (business) women, to have better professional chances. Which will probably be the case.. though, as you said, I fear that the additional segregation may backfire in some way.
Saudi Arabia - The only place where you can have 20 woman 20 years younger than you, you can beat em all day, and if you get bored by one of them, she is killed. Then you get 2 new wifes.
Can you back this up this with something or you just trolling?
