In Muslims countries of Indonesia and Pakistan there already has been a women head of state. But in America there hasnt been one yet. Women in America got the right to vote only in 1920, belive it or not.
The past has been a man's world. Thus man made the rules.
How about rape stats in the countires of the US and Saudi Arabia. Lets look at a comparison.
Rapes in Saudi Arabia per Year
Rapes: 87 (2000)

Rapes in the United State per Year
Rapes: 89,110 (1999)

Look at that difference.
So do Americans really respect our women more?
