First off I would like to start by saying that this whole project is amazing; "Dark Girls" was really eye opening and I love that everyone is getting the opportunity to share their experiences.
The first time I 'experienced' shadism was the day I was born. Obviously I do not remember this happening, but my mother remembers it vividly and I hate how sad it makes her. When I was born, I was pretty pale, with straight, black hair. When the nurse went to check on me, she gasped when she saw my Mongolian spots. She had assumed that I was white. She turned to my mother and asked her if she knew that I was half black. It's bewildering to think that even as a newborn there was something about me that let other people know that I wasn't really one race or another.
When I was little I never saw anything different about my family, except maybe that my older sister was only half-related through my mom. But even that was beginning to grow common.
