You are brave to come to the defense of liturgical dance! It's a very divisive subject I suppose. You either like it or don't. Perhaps if it was not integrated into the liturgy as such but a before or after thing? Or an individual parish could be asked (anonymous ballot) if they wanted it. For visitors, it is always easier to have a Mass which follows the rubrics for obvious reasons. I live in Japan where dance is (or can be) part of Shinto ritual but I cannot see it happening in Catholic churches - partly for that reason.
