there is not just "2 exempted conditions", except maybe, in your head.
Fine, ?maybe? you are aware of those Ayat(s) where other conditions are explicated. Kindly direct me to them, I will be thankful.
It says, I believe, fasting is prescribed but if you experience 'hardship' you can do it other days or pay the charity. It is for them to decide not you. How do you know people are not experiencing a hardship that you do not understand? Why do you get to decide if they are sufficiently ill - are you a doctor and have you examined them? Maybe a woman is in the early stages of pregnancy and is not showing yet and is yet to tell anyone, fasting may make her morning sickness worse, it may be sensible to delay it til after the birth, even if to you it just looks like she is being lazy or something. Open your mind man!
Kindly read the post again, specially the last paragraph and do not assume/speculate.
Hint It is about those able people who skip fasts without any valid reasons.
