Bowwow – A Mitzvah Tantz does not have mixed dancing. 1) The women are all seated. 2) The Kallah just stands holding a gartel. 3) It long after midnight after all non-immediate family left. (And if anyone violates the rules and does it incorrectly, then you might be correct that it is wrong of them.)
smartcookie – Then it isn’t a mazinka dance. It is something else you reinvented. The mazinka dance idea comes from non-frum origination.
