OK, I see. What do you mean by physically homogenous?Rakovsky, what I've heard all my life is that this is exactly what the UU church has been struggling with for many years. It's kind of a matter of definition - a 'who are we?'. As you probably know, the Unitarians and Universalists originally merged specifically to deal with Civil Rights in the early 1960s - but after that, where do they go?
It has turned out that the UU congregations are so diverse in background (yet physically rather homogeneous) that nothing they do can satisfy everyone. They are going to have to settle for satisfying a specific group and cater to that group more strongly; right now they are trying to be everything for everyone, it seems to me.
Not much clearer, sorry.
It seems to me that if they are actually dedicated to Unitarianism, that they should at least cut out any teachings supporting atheism or clear Polytheism. Of course they can make their church whatever they want.
But with 500 years of history like you said, they really could systematize doctrines and luminaries in the way that "traditional" Quakers have done.
They could create a clear basic school of thought or theology on Unitarianism just like other religions have done with their ideologies. They could focus on God and the writings about Him by the leading Unitarians like Ferenc in 16th century Romania.
I think the fact that they don't do this makes it harder for people to stay dedicated and focused on their UU church, because like you said, it doesn't come across with set beliefs. It's disconcerting that online the internet there are next to no UU internet forums, even though there are plenty of forums for Christian groups, skeptics, agnostics, and Atheists.
On a sidenote, I am actually very skeptical that a strictly "Mono-Unitarian" view of God would actually be correct if He exists. Even aside from Christianity's particular claims about Jesus, it makes sense that God could be seen as a "unity" of beings in the Torah, since God is called Elohim, a plural word, even in the Jewish Schema. Over some subsequent recent millenia, the rabbinical community could simply have avoided and reinterpreted this original non-Unitarian view in reaction to Christianity or for the sake of simplification.
