I wrote this article as an account of a personal experience I had, so the reason that the reactions I noted are negative is because these were the people who had the most impact on me during that experience. I did have positive feedback at the time and afterwards, which I could have included. I chose not to explore in depth theory on the subject in the article as I mainly wished to write about how shaving my hair off made me feel on an emotional level. I hoped that readers would find it interesting to relate on a personal level with the writer, as opposed to being simply informed and educated.
I think it’s really important to look at how our culture creates the environment that leads to violence against women and other issues. Also, studying and thinking about cultural media is important in its own right, and why not look at it with a feminist lense, the same as with other lenses of analysis? I’d also suggest reading the entry in Feminism 101 for a general response to the question “why are you talking about X when Y is so much more important”.
