Hi hairy-- I was a Unitarian for a while on my journey from Roman Catholicism to Reform Judaism. (I even conducted a few services and toyed with the idea of becoming a Unitarian minister... mostly because the name of the west coast seminary is so cool: "The Thomas Starr King Seminary." ) The rabbi at our synagogue has written a book (mostly a collection of excellent sermons) and one of the chapters is about how close Unitarianism and Reform Judaism are. The Unitarians are a "community of seekers" with no dogma or doctrine. That's why I loved them. (As a former R.C. I missed the candles, chanting, arcane rituals, and the foreign language-- LOL-- so moved to Judaism.)
Your W's reaction was, as usual, over the top. Personally I think she's jealous that you've found a place where you fit in and feel comfortable.
