Dan, 100% responsibility and blame are not the same thing. You are not to blame for the events in the world that you object to.
What you are responsible for is: your response to them. There are many things that happen in the world that you just don't like. It seems to me like you get pretty outraged by them. And that's fine. But it doesn't feel very good, does it? Well, maybe it feels good in a nurturing-a-grudge sort of way, but that's not an authentic alignment with feeling good.
It looks to me like you've skipped an important step in taking 100% responsibility -- accepting reality exactly as it is and exactly as it isn't. That does not mean condoning any particular behavior or event. It does mean letting it in. That is: these things have happened, and they should have happened, because they did happen. Arguing with reality ("this *shouldn't* be! this *shouldn't* have happened!") only leaves you feeling powerless and outraged, because there is no freedom or inspiration around "it *should* be other than what it is!"
Maybe you're saying to yourself, "Angela shouldn't be saying this! Of course people shouldn't dump toxic waste! Of course the war in Iraq should never have been started! What kind of idiot believes people should be forced at gunpoint to harvest coffee beans!"
And as you think that, notice the feeling in your body and mind. It's not a good one, is it? That's because reality is not interested in your *shoulds*. It just keeps on being real, no matter how much you rumpelstiltskin it. All that *shoulding* eats up the beautiful energy you have that could be making a difference.
Once you choose to accept that things you don't like have happened -- once you let it in that this is how it is -- you are free to make choices that are in alignment with who I know you to be: a man who is committed to making a difference in the world. You are free to see who you are as a matter of consequence. Letting go of "it should be other than what it is", you are free to generate what you would like to be in the face of reality.
So, here you are, a vital, powerful, loving person who accepts that toxic material has been dumped. There is no freedom in, "that shouldn't have happened" -- but where can you see freedom for yourself? Maybe in "I'm committed to clean water in the world" or "education" or "organization" or whatever it is that really inspires you in the face of the reality of toxic dumping.
100% responsibilty = accepting reality exactly as it is and exactly as it isn't, and taking a bold look at who you are being that reality occurs as it does for you.
Best wishes to you in generating something huge! I'm confident that you are doing that.
Lots of love and gratitude,
Angela
