I'm not necessarily against changing profile pictures for this, but I've begun to wonder 'why France?', when so many countries in Africa see worse on a weekly basis. It's hard for me to believe there isn't truly a misplaced value on life, that we as a nation (and maybe the world) truly do value the lives of white people more than those of people of color. I'm not speaking of you as an individual or any other individuals, but of us as a whole. This was a terrible act of terrorism, and I don't want to minimize it, but when compared to other events (college and village masacres, for example) I don't understand why this was picked for a nationwide 'show of solidarity'. Again, I'm not saying I think that individuals who add the French flag are racists, only that I believe it's a sypmtom of a deep problem with the way we as a group see the world.
Edit: Here are a couple of links to articles you might find interesting. It turns out I'm far from the only person asking this question.
Also, when I say 'weekly basis' up above, I don't necessarily mean terrorist attacks. I was thinking more about villages being slaughtered for their children and that sort of thing. As far as I know, it's still a huge problem.
