A males body does have on average more muscle than a female. That's why it takes long for a girl to get a six pack than a man. And there's nothing wrong with it. There are some kick butt woman out there. ;]
It's not just the males' fault. Most girls want to feel pretty, they want to feel feminine- event the stong Mia Ham and Serina and Venus Williams are very feminine off the field/court- and so we act this way. There's nothing wrong with being feminine or being more masculine but if we want to be 'equal' we have to fill that role. First by accepting those women who don't want to be that feminine and would rather be more masculine. No calling anyone a 'gay/cross dresser/etc.' out of spite just because they aren't into the make up or dresses.
Then we have to realize the other side. Guys are pressured SO much to not 'act like a female' because that's 'not manly'. "Oh, you can't cry or you are a homo! Oh no, you aren't as strong as me, you must be female! You're sensitive? You girly baby!" When someone has all that on them, that's where the sexual slurrs come out.
Men and women have different roles, different niches if you will. And that's okay. Strive to be what you were made to be. Just because we are created differently, doesn't mean we aren't equal. But when things do become unequal and sexism is shown, remember it's because they themselves are afraid, they themselves are being pressured to do and say these things. Of course that doesn't make it right, but see how it is in their shoes.
If we want to be totally equal, we have to change the rules on what is
considered 'feminine' and what is 'masculine' and change the rules on how we view other people that 'don't follow those rules'.
