Henry McCullers, an affable Plano, TX-area anti-Semite, praised the
Jewish people Monday for doing "a bang-up job" running the media.
"This has been such a great year for movies, and the new crop of fall
TV shows looks to be one of the best in years," McCullers said.
"And the cable news channels are doing a terrific job, too. Admittedly,
they're not reporting on the Jewish stranglehold on world finance,
but, hey, that's understandable."
zilpavbroda = zi'o zei pa zei broda :: broda fa zi'o
zilcibybroda = zi'o zei ci zei broda :: broda fe zi'o
zilmumbroda = zi'o zei mu zei broda :: broda fu zi'o
The meaning/effect of zi'o itself turns out to be a tad controversial.
According to me, it serves to redefine the selbri so that it needn't
express a relation in which the zihoed place plays a part.
An example:
pikta
x1 is a ticket entitling x2 to entitlement/privilege x3 under conditions x4
zilpikta (< zilpavypikta)
x1 has right/entitlement/privilege x2 under conditions x3

By my understanding, what you are calling a projection is really a selection
followed by a projection. Projection as such just shrinks the number of
domains in the relation. The reason why new tuples can then appear in the
Lojban context is because Lojban is an open world, where new relationships
can appear from thin air, whereas implementations of relational algebra
are closed worlds, where the tuples that initially exist are all the ones
that will ever exist unless they are explicitly added.

pe'i, deviation from strict jvajvo principles for the sake of brevity
should not itself be constrained by further principles, except the
general principle that the shrunk lujvo does not block any other
meaning with a better claim to be the meaning of the lujvo. In the
current instance, then, {zilpikta} could correspond to zilpavypikta,
zilrelpikta, zilcibypikta, or zilvonpikta. Whichever of these four
is the Coolest (i.e. the most zabna) has the right to be equivalent
to {zilpikta}.
--And.
I would normally use {zilbroda} for {broda fexiny zi'o} with n>1, what n is
depending on the meaning of broda. So zilselcmi = zilrelselcmi = set (a thing
which has members, except it might not because it could be the empty set).

This serves as a superficial analogy, but it's not quite the same thing.
zi'o expands the meaning of a selbri, a projection doesn't. A projection
just fixes the value of one of the arguments, or restricts in some way
the relationship between the arguments. zi'o goes the other way.
It would be more appropriate to say that the zi'o-less selbri is a
projection of the zi'o-selbri. Only a subset of the arguments that
satisfy the zi'o-selbri will satisfy the zi'o-less one.

Yes, very good. {pikta} is a projection of {zilpikta}, from all
relationships
of entitlement to only those relationships involving tickets.
Also:
zilrelpikta
x1 is a ticket giving entitlement/privilege x2 under conditions x3
To include tickets that are not personalized.
and:
zilreljvecibypikta
x1 is a ticket under conditions x2
To include tickets that don't necessarily entitle privileges.
(It is still a mystery to me why some gismu have an "under conditions"
place and others don't.)

What is the controversy?

And according to me. To be precise, zi'o provides the operation of the
relational algebra called "projection", whereby an n-place relation
becomes an (n-1)-place relation.

An excellent example!
