HaKatan, it’s an offene Rambam that avoda zara requires intent. Mecca started out as explicit avoda zara, but in the times of the Rambam is wasn’t because the kavana wasn’t there. I’m sure you could dig up Geonim saying Mecca was avoda zara, but that doesn’t change the metzius later.
You admitted an Israeli flag isn’t avoda zara. So why do you keep repeating it’s avoda zara when you just admitted it’s not?
