Prophecor, male or female we're all useful.
I don't deny that we are all useful, what I question is in the presence of a given situation, IE your on the frontline of battle and you have males as well as females who are engaging the enemy in a firefight, do you feel that the battlefield is a place that is naturally suited towards women?
Can women perform on par with men when it comes to the heavier duties of war, or even dealing with a police shoot out with a bunch of Crips & Bloods, a hostage situation a bank robbery or things along that nature?
To me it's not so much about equality, as it is about what gender of the sexes is better able to deal with, navigate and most effectively handle some given situations.
If that be the case, then we can let women join in our football teams, basketball and other like sports. With one exception, maybe. That of Dannika Patrick, the first women to participate in a male dominated field of motorsports. The Indy 500 just past. She participated, well in a male dominated sport of man against man but with a machine. Some arenas I believe men and women can equally co-exist. There are others for which I will always believe that both sexes just naturally operate better seperately or not even at all.
I don't regard the woman as useful within every situation. Somethings, I will always believe are better suited if it is that men are doing them.
