Liturgical dance should be limited to dances that can easily be done on an altar without offending the Blessed Sacrament --- the Watusi, the Swim, the Fly, the Mashed Potatoes.  All these are appropriate as a "meditative practice to help people reconnect with their bodies," which is the very purpose of Mass to begin with.  By no means, however, should disco balls be allowed.  Or the Tango.  Come to think of it, maybe we should allow that.  It'll keep Southern Baptists away.
