I started a public Flickr group to focus on visualizing social constructs. There are already many photographers from all over the world contributing. If you have work that deals with social construction, please join and submit your work: http://www.flickr.com/groups/socialconstructs/
This group shares images and ideas that deal with socially constructed boundaries. Race, class, sex, beauty. Social constructs shape the way we perceive ourselves and others around us. Pink for girls, blue for boys. Do my teeth really need to be whiter? These modes of thought come out of specific social contexts (political, cultural, social, economic, scientific, etc). When the context is analyzed, their artificial nature can be revealed and often unravelled.
