Going for the most vanilla aspects of self possible - my "real self" would rather eventually be a full time artist, likes model trains and Occupy Wall Street, and doesn't give a crap about football. If I had to have an identity for REAL NAME which could freely be searched by anyone who wants to hire me, or anyone who beat the fuck out of me in high school, you can bet money it would not be a fair representation of who I really am. Their argument is completely fallacious as always, which is I guess to be expected over people who are basically trying to make an excuse to reduce my online presence to a conveniently tracked marketing demographic.
