The end of gender?

I bloggers! Today I must talk about the end of gender, commenting video of this link: http://www.ted.com/talks/johanna_blakley_social_media_and_the_end_of_gender#t-486930

This link tell that nowadays the gender is not useful to the social media because is a very restrictive label, and today the people escape of categories demographic box.
I think that is very important understand the category “gender” like a social constructions. That is, the gender is a product of the culture and so that`s why have an ideology and is possible to deconstruct it.  

Is really that nowadays the gender is different to in the old time, but is really too that in this time exist categories of gender that the society reproduce. That is obviously in the market, but all the time we are reproducing these categories: with clothes, language, our movements… all the time! Including the space is order to maintain these categories.

Sometimes we criticize other people (models, soccer players, etc.) because they wear or behave “like a girl”, for example. But we also wear and behave using the gender categories. We reproduce this restrictive label. All of us tell “gay” when a man behaves “like a girl”, and criticize when a women does not shave her leg. All these form of act are the application to gender categories, and that is why I think that the change is deeper that modify the publicity.

That is why I think that the exposition of the women of video is not useful: this only serves to market and bigger business… and these companies only going to use this information to change the mechanism to offer their products, and not to recognize and eliminate the oppression of the gender categories.
