Transformers don't care about people -- any kind of people. I wrote a quick article for Wired about why Transformers rock because they don't want to either be people or kill people. They've got their own damn problems.
Of course, I saw the latest movie preview today and it's all about how some Transformers want to "protect" humans and some want to "destroy" humans. That's what cracks me up about humans -- it's always all about us... But it's a movie, so what are you going to do?
