I'd like to start a conversation on the the need to rapidly rethink our values on a global scale.

You should spend time writing about it and finding accounts that are along the similar areas. Comment on their blogs with what is relevant to them well and the conversations will start. it takes time to build though.

It is now more important than ever to assume this responsibility.

I agree with this and yet, we seem to be moving away from responsibility en masse while a minority move more toward it. That may change in time.
