Sex objects are noticed because of their
body, and not their
ideas, opinions, or talents, if only for that moment. Most likely all of us have objectified, or been objectified at some point in our lives.
With the
internet, take the same situation, only instead of someone even seeing what you look like to objectify you, its done based solely on the implied gender. Being a
female geek, I tend to be noticed for my
gender, rather than my ideas or accomplishments.
