Would you give a dollar to tzadakah for every pot, pan etc. that has ever had to be toiveled in mikvah because of some crooked mashgiach, whether chasddish, litivish or Eastern Shore leading to treifus being sold to a frum yid? Please name your favorite tzadakah.
I’m not sure how that is a defense…
Also, what does tevilas keilim have to do with anything?
