Yeah I'm to be honest just trying to awaken people to the priority being that we need to establish a self-sufficient colony somewhere other than Earth.
Establishing colonies is only imperative if the continuation of the human race is. I'd argue that humans have value only due to other humans. There is nothing inherently valuable about human life from a non-human perspective.
That is not to say I don't support space colonization, just that I don't think its a moral imperative.
How would you know?
Though I don't share your assessment that that is a productive place to direct citizen input on this (or any other) issue.
