Unfortunately, my parish does not bear one of these signs.
So what do you do when there is liturgical abuse? Inform yourselves.
Here are some links to why liturgical dance is to be done outside the liturgy:Such is the case of the Israelites: in the synagogue their prayer is accompanied by a continuous movement to recall the precept from tradition: "When you pray, do so with all your heart, and all your bones." And for primitive peoples the same observation can be made.(click to read the entire Document from the Congregation of The Sacraments and Divine Worship)
However, the same criterion and judgment cannot be applied in the western culture.
Here dancing is tied with love, with diversion, with profaneness, with unbridling of the senses: such dancing, in general, is not pure.
"For that reason it cannot be introduced into liturgical celebrations of any kind whatever: that would be to inject into the liturgy one of the most desacralized and desacralizing elements; and so it would be equivalent to creating an atmosphere of profaneness which would easily recall to those present and to the participants in the celebration worldly places and situations."
And from Cardinal Francis Arinze: A MUST SEE
