But if said destruction is “fun” isnt that hannah
It’s not hana’ah from the item of issur.
though as I recall using a mikva that one made a neder on is assur in summer
That’s physical hana’ah from the actual item of issur.
But isnt hosting a dance with music inviting friends dancing to celebrate said destruction and having a grand old time, having haanah from the item?
No.
