Ramadan is not fasting. Ramadan is an Islamic feast where one stuffs oneself twice a day with food, and in between lets ones intestines dry out. To describe that process as 'fasting' seems rather ubiquitous to me. The amount of food transported into the body is probably exactly the same, but because of the dehydration the food is processed less effectively. As customs go, most customs are typically silly and Ramadan is no exception. I can accept such silliness when people keep it to themselves, but unfortunately one sees such a sharp rise in 'policing' others that even non Muslims are now experiencing violence because they are eating at daytime in the Ramadan period.
