What I'm responding to the the notion that "no action you can take matters." Specifically this:
>Individual human beings acting individually are totally irrelevant when it comes to the behavior of large organizations.
I just don't believe that. Small actions do matter and are necessary because they enable the big actions later. You have to start somewhere. Even if it feels insurmountable. No major change ever just happened in isolation, it always happens when enough people have had enough and fought back enough that the change was inevitable.
Worker rights didn't just spontaneously appear because enough people wanted them. They came about through organizing, coordinating and leading. Same for Women's suffrage, Civil rights, gay rights...
