Social Construction of Reality

As I grade my blogs this rainy Sunday afternoon, I realize I didn't do a great job with the social construction of reality. So if anyone happens to read this let me know if this is at all helpful.  I'd like to start with a quote

"In its briefest form, the social constructionist argument is that there is no ultimate reality or truth out there for us to discover; instead, society and the world around us are what we make them. (Of course, different social constructionists take this observations to different extremes, some applying it to only a few aspects of society, others applying it to things many people consider to be inviolable scientific facts, such as gender and racial differences or the nature of the body.) This observation, if true, is important because it has major implications for our perception of what we can and cannot change about the world. As a basic example, if gender differences are biological, then we cannot change the relative places of women and men in the world, but if gender differences do not exist except in our minds and in the social structures (such as employment rules, government policies, and attitudes that affect how we interact with each other, what we teach girls versus boys, etc.) we create from our minds, then we can make these differences go away. http://www.epinions.com/review/The_Social_Construction_of_Reality_A_Treatise_in_the_Sociology_of_Knowledge_by_Peter_L_Berger/content_21860224644

At base, the social constructionist perspective says that society does not have to be the way it is, then asks how it got to be that way, why it was made that way, and how we can change the things we don't like about it. "
 In other words- race is a social construction- there is nothing inherently different between Black, White, Asian, or Latino people. People's brain size does not vary by race, nor does athletic ability nor any other characteristic directly link with the skin color gene.  Romans considered one's race where one was from- so Buffalo Grovians would be a different race than the people from Wheeling.  Around the year 1500 c.e. people started to group people by shades of skin color and call that race.  But even then, the Irish were not considered white.  So we construct this idea of race just like we construct the difference between spit and saliva.  But again society does not have to be the way it is, then ask how it got to be that way, why it was made that way, and how we can change the things we don't like about it. " So what social construct will you change in your lifetime?
