1. At a public talk someone asks you, "okay, I understand what
         you reject, but I wonder what you are for? What institutions
         do you want that you think will be better than what we have,
         for the economy, polity, gender, race, ecology, or whatever
         you think is central to have vision for?

A democratically elected government, running programs to provide adequately the necessities for a fulfilled life, at least as efficiently as it now runs Medicar, public education, police and fire departments, etc.

      2. Next, someone at the same event asks, "Why do you do what
         you do? That is, you are speaking to us, and I know you
         write, and maybe you organize, but why do you do it? What do
         you think it accomplishes? What is your goal for your coming
         year, or for your next ten years?

Because all of our lives are interconnected. Whatever it actually accomplishes, one has to try

      3. You are at home and you get an email that says a new
         organization is trying to form, internationally, federating
         national chapters, etc. It asks you to join the effort. Can
         you imagine plausible conditions under which you would say,
         yes, I will give my energies to making it happen along with
         the rest of you who are already involved? If so, what are
         those conditions? Or - do you think instead that regardless
         of the content of the agenda and make up of the
         participants, the idea can't be worthy, now,or perhaps ever.
         If so, why?

I'd need a convincing explanation about why another organization is needed, given the existing broad spectrum.

      4. Do you think efforts to organize movements, projects, and
         our own organizations should embody the seeds of the future
         in the present? If not, why? If yes, can you say what, very
         roughly, you think some of the implications would be for an
         organization you would favor?

Of course.

      5. Why did you answer this interview? Why do you think others
         did not answer it?

Because it could be done quickly, and it might conceivably go somewhere. Because they didn't have time, or see the point.
