rational – “simple logic (surprise, the halachah and many poskim are logical) demands one day here in Israel”.
I hope you are joking when you approach halacha with “simple logic” because as Chazal said, simple logic makes no difference if you shecht the animal from the front of the troat or from the back, but Hashem wants us to do it this way and not that way.
We don’t keep mitzvos because of logic. Halacha isn’t decided by logic – that is not one of the precise 13 midos sh’ha’Torah nidreshes ba’hem.
If you are serious, that your Judais is based on logic, then why would you keep shatnaz, or not mix milk with meat, or refrain from using electricity on shabbos etc. You sound like a non-frum person that rejects Torah because it doesn’t make sense to him.
