Let me ask this. Of what use is an attempt for us to define what it means to be progressive when you hold your own view that won't change no matter what we say? If the entire world is a struggle, a war, between Left vs. Right, Progressive vs. Conservative, Us vs. Them, how are we ever going to find common ground and decide to act in cooperation and collaboration towards a shared future?
Progressive TO ME means keeping four things in mind.
Grassroots democracy - if a decision is being made that affects you, your voice should be heard.
The concept of WE - The Earth is a single environment. We should treat it as such. We are in this together.
Understanding the Past - both positive and negative. Learn the lessons of the past so we don't repeat those mistakes.
Looking to the Future - We are creating the world our children will grow up in. What kind of a world do we want that to be?
I don't expect you to agree. And I don't know if you will consider this to be a "political" answer, or just an answer. Maybe I'm wasting my time. But since you asked what we are progressing towards, I thought I would weigh in. I want a world that my sons can live in, and I want them to thrive in that world. And I want that for all children, everywhere.
