Bells, and Misleading with Selective Truth Telling

I usually read Fr Dietzen's liturgical question and answer column which our diocesan paper runs.
Sometimes it seems to me to ... skirt the literal truth, usually in a spirit of Charity.
(e.g., You wouldn't tell someone who is racked with guilt that if he doesn't confess, he'll go to hell, [or be deprived of Heaven,] you tell him that God is all merciful, and He will welcome him in confession.)

Good.

But sometime this evading the truth, the whole truth and nothing but the truth seems agenda driven.
To a question about whether Consecration Bells should be used, the good father cites the correct bit of Notitiae

Where liturgical education has been adequate, there is "no need for this kind signal. If sufficient liturgical instruction is in fact lacking, bells should be rung at least at the two elevations, in order to elicit joy and attention: Not 8 (1972) 343.

Got that? If your parish is dim or ignorant, you should use bells, but not otherwise.


But that is NOT what the actual Notice from the CDW said, he leaves something out.

109 Query: Is a bell to be rung at Mass?

Reply: It all depends on the different circumstances of places and people, as is clear from GIRM no. 109: "A little before the consecration, the server may ring a bell as a signal to the faithful. Depending on local custom, he also rings the bell at the showing of both the host and the chalice." From a long and attentive catechesis and education in liturgy, a particular liturgical assembly may be able to take part in the Mass with such attention and awareness that it has no need of this signal at the central part of the Mass. This may easily be the case, for example, with religious communities or with particular or small groups. The opposite may be presumed in a parish or public church, where there is a different level of liturgical and religious education and where often people who are visitors or are not regular churchgoers take part. In these cases the bell as a signal is entirely appropriate and is sometimes necessary. To conclude: usually a signal with the bell should be given, at least at the two elevations, in order to elicit joy and attention: Not 8 (1972) 343.

As a rule the bells should be given at least at the elevations.
Nothing about only for us poor ignorami.

What is with the Trendists' (who have usurped the title Progressives,) aversion to bells, I wonder?
