I think we might have ended up off-track, so let me try to sum up my stance:

I did the same in my new reply to your previous post. Let me just address one side point:

Unitarian Universalists, by default, must have "arbitrary positions" because they are not discussing settled matters. Therefore, the fact that they have arbitrary positions in and of itself is simply a function of their focus; all social justice groups will run in to this issue, whether they are religious or not.

The best method of operation for a social justice group which wishes to find optimal conclusions may be to hold off on proposing solutions. Getting stuck in a position that's incorrect or not useful seems like a serious concern. There shouldn't necessarily be a consensus position on a given issue, regardless of the goal of the group.
