To observe & report!

The UUs call themselves congregations rather than churches. The objective is to find community / common cause. It's a post-Christian group; they are actually heretical from a Christian perspective since they don't subscribe to any of the historic church creeds (or to any creed) and the titular denominations, when they merged some 60 years ago, were also heretical (one denied the Trinity, the other preached Universal Reconciliation).

Community is about the only thing churches have of actual value. I applaud (in concept anyway) reclaiming that one thing of value and welcoming atheists, agnostics and basically anyone who wants to coalesce around that.

In practice ... in my experience at least they tend to substitute political ideology for religious ideology, and there are gaslighting asshats and smug hypocrites, just over different things than one normally finds. Also I suspect that some of their congregations make less of an effort than the one depicted in the video to have woo-free meetings and activities. For example the local UU congregation where I live has 1 service and it's somewhere between traditional and contemporary; another one I attended in the South also had 1 service and it followed a more evangelical-like liturgy (though obviously, not in terms of content).
