But even if Moses himself told you to do something, don’t you think G-d gave you a brain to actually use it and decide if that commandment makes any sense?
“frummy in the tummy” is absolutely correct. Why listen to a commandment from Moshe Rabbeinu m’sinai if it doesn’t make sense to your own G-d given brain? Use your own brains and decide!
I’m sure tummy doesn’t wear tzitzus.
