As Columbus day exists to celebrate a major event in the history of white people taking things from people of color as if its their birthright, the story of a woman of color who was called a whore for not working for free seems sadly appropriate.
So I urge you to read the words of DNLee, a science writer who was asked to contribute to an online science blog. When she found out she would not be compensated for her work, she declined to participate, in what most of us would call a reasonable decision for a professional to make about their time and effort.
Instead, an editor from the blog in question sent her an incredibly inappropriate response. In response to that, she wrote the great bit linked to above about the role of race and gender in science reporting more generally. Go read it.
