jewishandworking22 you are proving my point.
When Rabbonim dissagree each person or community dfollows on particular Rav.
What that Rav tells his congregation is very black and white.
I have never in history heard of any Rav say to anyone “There is no Psak on this Halachic Sheila, so you can do or not as you please because it’s a grey area”.
When it comes down to a pask “What should I do in this situation” There is always either a pask what you shopuld do in black and white or you are told to go to another Rav who knows more about that specialty and can give a black and white pask.
It might look “grey” the the Gemarra but we do not pasken from then Gemarra specifically for that reason, the final Halacha that each person needs from his Rav is totally back and white.
