I'm not arhuing any utopic town, where did you get this? I'm not denying being a head of state comes with certain risks. I'm asking why exactly men are allowed to take those risks and women aren't. You haven't answered this.
Seeing more men than women being head of states is not an Islamic thing, its more of a choice from the electing people themselves and anything else is simply a cultural thing. Being a female while in office brings far greater risks and not a lot of woman are wanting to find out just how great those risks are. Whether they are allowed to or not has nothing to do with Islam.
