Okay. If a few more believers show up we could claim a trend, maybe a movement.
I feel your pain.
The solution will elude us until people writing about cosmology become more precise in their use of terminology. At present, they use "universe" interchangeably to mean both the "universe at large" (everything that exists) as well as "the observeable universe." Thus the confusion.
If I had my druthers, I'd reserve "Universe" to mean everything, and "Hubble volume" for the "observable portion of the universe." An alternative would be to reserve the CAPITAL U "Universe" for everything that exists, and the small u "universe" for the observable portion of the Universe, but I think my original proposal is less likely to confuse.
