Of course one is entitled to one's opinion.  However any opinion is equally open to exploration of its expressed basis and reasonableness. 
If... "Our bodies...are Temples of the Holy Spirit and should be used to glorify God", as Deacon avers, why relegate that glory to the "parish hall" and exclude it from the core of the parish community -Church? Seems contradictory.
Palm Sunday at my parish had a "procession" of children waving full palm fronds accompany the celebrant down-around-up aisles, bodies swaying, while  celebrant wafted holy water side-to side. If one backed out of one's rhetorical box it seemed mighty like "dance" by another term.  Was that an obscenity?
"The Holy Sacrafice (sic) of the Mass is no place to innovate or to express yourself."? If one holds to its sanctity, would not one know how to spell it? If no innovation would it not be a replication of the original? "Attending", "participating" - are these very terms not terms of expressing oneself?
"We are Catholics"!?
