Gender wars

While reading through the blogs one of the questions that someone posted caught my eye. The question that was proposed was "is it mortifying if someone mistakes you for the wrong gender? If so, why?" I thought this was a brilliant question because I know I have personally been out with my friends and have seen someone who I did not know if they were male or female. This of course then struck up an interesting conversation between us...like it really mattered if the person was male or female, but for some reason at that time it did. Now, reflecting back on that situation I believe that since society has drilled into my brain and probably others how to look, dress, and even act based on your gender this is where the term "gender wars" came from.
At first I did not like the idea of men and women being at war. When I first heard the term war all I could think of was men and women fighting to win a battle and people dying. After answering the above question I began to think about "gender wars" in a different way. I thought maybe it could mean that women and men are having a "gender war" between themselves and society. For example, when I go to the hair salon and get my hair styled I make sure that the hairstylist does not cut my hair to short. Even though I have always wanted to try and "rock the mohawk" like Rihanna. I know that if I followed through with this action someone on the street might consider me to be a man because society has taught us that mohawks and shaving your head are things that men do. So, therefore I believe that society and the genders are at war with each other as to what is acceptable and what is not.
Society and the genders are probably always going to be butting heads as long as these stereotypes exist. I know throughout the years more and more stereotypes are being broken. For example, it is becoming more acceptable for men to wear the colors like pink or purple. If a man were to wear pink ten years ago society might characterize him as being "homosexual". Now more men wear pink because society has said that it shows that they are more in touch with their "feminine side".
For the two questions that I propose are:
1) How do you think "gender wars" or "gender differences" are seen in other countries?
2) Do you agree with the idea that since both genders are always changing and developing that there will always be some sort of "gender war" or "gender difference" present?
