Here's where lay out my problems, but not structure my complaints too much and certainly not offer helpful and constructive solutions. I've experienced "why can't you be positive?" as controlling behavior for too long to get sucked into it now. That'll keep.
There's something about The Big Pink Logo -- something hypnotic -- that brings people out of themselves, and leads them to speak more candidly then they might otherwise. I suspect because it's safe to criticize, and acts as a proxy for other grievances. Dawn Cooley has written an excellent blog post ("Surprised People Act Poorly") on her take on the logo back story.
I don't want to miss this moment, because the classic solution is to walk away or resume a resentful silence. I've seen a lot of people walk away from Unitarian Universalism. Good people who have hit a dead end, some having grievances that were never properly aired, much less resolved.
I decided to put myself through a one-man brainstorming and clarification process. I took a pack of sticky notes and wrote down the problems that came immediately to mind; this is not complete, and you may have other things to add. (It took about 15 minutes.) Again, I did not add the things I like about Unitarian Universalism because I didn't want to be deflected. Some relate to the UUA as an institution, some from other institutions and others are customs and culture.
Afterwards I sorted the notes I copied them into mind-mapping software and cleaned them up. I added some items and removed other that I have heard but don't have any experience with. This is what I'm sharing with you now. This is my view of affairs. Some of these may not make very much sense as-is, and I hope to draw out my meaning shortly. The links are obvious, but sometimes I put items in close proximity because they relate.
I also welcome you to expand on this chart by sharing your thoughts in the comments.
