#UUdecline
Maybe it depends upon what the meaning of the word "biggest" is.

After all, #UnitarianUniversalism is a tiny, declining, #FringeReligion that has fewer than 200K members in the USA:

There are well over 5 million Muslim Americans.

Considering that #UnitarianUniversalism has less than 200 thousand members, including both adults & children, in the whole world, I doubt there's any single town in the USA, or anywhere else in the world, that is "populated by #UnitarianUniversalists".

The American Unitarian Association merged with the Universalist Church of America in 1961 because both denominations were in decline.

#UnitarianUniversalism has continued to decline both in membership & in #morality. . .

According to former #UUA president Rev. Dr. Peter Morales, #UnitarianUniversalism is "a tiny, declining, #FringeReligion", & he said that in 2008 when #UUism had about 34K more adult members & 25K more RE enrolments than it does today.

For a "religion" that's "theoretically perfect" for "a lot of people on the left", #UnitarianUniversalism sure has embarrassingly low membership statistics, & no doubt even lower Sunday service attendance numbers.

I wonder why?

What is Islam's answer to the #UnitarianUniversalist "Church", at least in terms of how many #Muslims in the #USA choose to practice it?

Is there a small #Muslim sect that has only 130K adult members in the USA?

Peter, you've been promoting #UUgrowth for how many years-decades now?

What do you have to show for your efforts?

As may be seen in official #UUA membership statistics, #UUism has been in steady decline for several decades now.

There's not even a quarter million #Unitarians aka #UnitarianUniversalists, and fewer than 1000 UUA 'churches'.

In fact, these official #UUA membership statistics are probably somewhat inflated. . .
