Reference is to particulars. Now, if you want
generality, you have two choices — one not
officially available in Lojban. You can use
quantifiers — and whichever one you pick will
generate the problems mentioned above — or you
can use some modal notion like "generally" or
"usually" or "typically." Lojban doesn't have
those but clearly needs them. As modal notions
they do take one out of the real world into
idealized ones of some sort — but then, in that
world, {lo rozgu} picks out some roses, all of
which or some of which are or are not red and on
that hinges the truth about {lo rozgu}. I note
in passing that your second definition of {lo}
makes it not only particular roses but specific
ones, "the obvious ones in the context" (assuming
that {zo'e} is meaningful and a referring
expression in a definition context). Your first
definition (otherwise generally better) contains
the unexplained "generic reference," for which I
cannot find a plausible interpretation still
after all these years (quantifiers or reference
to a genus or species having both been rejected).
The basic problem is that a claim, to be
meaningful, has to have some way of verifying it,
at least in principle. How would you verify {lo
rozgu cu xunre}? If nom particular roses are
relevant then it seems impossible to do, if some
are then the question is how many of them are
needed to show the claim true (or how are they
distributed, which is an only slightly more
complex case). You can say that quantifiers
don't count, but in the real world they almost
always do.

Obviously true, but the iorignals tend to get
saved and used later.

I have been explicitly told not too on pain of
being excluded from all sites under dGF's control
-- which, alas, is virtually everything having to
do with Lojban.

I think that was the point of the mythical
elephant, but I'll see what I can do.
