“tantz is brought down in numerous Seforim HaKedoshim. (i.e. Bach – Even Haezer 21, Chelkas Mechokek, Beis Shmuel, etc.) If you have an issue with it take it up with the gedolei poskim who permitted or even mandated it.”
Joseph,
There is no mention in any of the above sources about Mitzvah Tantz. The only thing is regarding a parent hugging their child in public. No one certainly ‘mandates’ it. I am aware there were some Admorim who did perform Mitzvah Tantz, however, they had certain Kavanos Al Pi Kabalah i.e. something with the Shem , which non of us simple people have anything whatsoever to do..
