Had a chat with an old friend, and we agreed that gender expression IS fluid.
The definition of what a man is and what a woman has been twisted by society's traditional views and manipulation by the media. By standards of these days, a man needs to have a chiseled body, while a woman needs to have a certain look to look pretty. Anything less, you are not manly or womanly. These views of "perfect gender" are so mediocre.
A dire situation has comed out of this obsession for gender perfection, for example, is in form of murders and totures of homosexuals in Russia. A supposed movement for human rights for the LGBT community (most of all, the right to live as part of the human race) has resulted in an illogical fear in the society, and oppression on homosexuals.
Russia is not the only place where the idea of perfect gender proliferates. Homosexuals face discrimination any where that has a strong traditional view or has strong religious presence that excludes homosexuality.
Gender should only be a term used in biology. It no longer has application in the modern world. It is also outdated, like education sticking to methods of the industrial days. Outside biology, the definition of gender becomes fluid.
A demure person is a person, an agressive person is a person. Love is defined by feelings and acts for one another, regardless the couple's gender. Females being allowed into the workforce to boost economies, and not get held back by traditional views of a woman's role in the house. Man being allowed to be a house husband, if his strengths is bringing out the best in a child, in raising a child of possibility.
"Fluid gender" allows for so much more possibilities.
PS: I've had people trying to use the argument of not being able to understand the other sex, like "Men will never understand childbirth!". Duh. Your point being? That woman are better? In their sacrifices? Or that men are worse? Put aside the fact that you are saying nothing about gender perfection or gender fluidity, you are doing nothing more than discriminating. It is precisely thoughts like this that creates 20 types of feminism, deviating the constructive efforts to position women as they truly are, a person, a human being, a contributing member of society. And these women deserve to express themselves however they would like to, regardless of gender.
