We may forgo eating fish or meat on Shabbat when we don't enjoy eating it
And so my fellow Jews "Ask not if we MAY dance on Simchat Torah; ask if we MUST dance on Simchat Torah?!"
What if we just enjoy singing w/o tripping over our own 2 left feet? What if we are drained from S'lichot, Yamim Noraim and Yamim Tovim and we're too tired to prance around?
Are we still on the hook to dance? Can't we still have "simchah" w/o dancing?
For those who ENJOY intense dancing - G-d Bless them. Let them express their joy and enthusiasm. For the rest - why bother?
