"Liberals" are people who reject Church teaching for their own secular purposes (such as "Catholics for Choice" and usually related to birth control, abortion, female priests).
There are essentials in Catholic liturgy, and there are areas where variety is allowed. All liturgies have time for singing and times for silence.
The Catholic faith allows for dynamic differences in non-essentials. Thus, someone who prefers a certain type of liturgical expression like a Father Fessio, remains on faculty, teaches at the school, and continues to be a big part of it.
If this is the case, it's absolutely right that it is posted - why don't you educate us on what is really happening then? Hiding behind closed doors will only cause more whispering and lead to more disinformation. Put it all out there and let the truth be known.

He participated in human chains around a local hospital that did abortions and called Clinton an "immoral man" during a homily the week before the 1996 elections.
