I can't remember but if I did apology tendered. Now clear my question about the three points you raised please.
No problem bro.. you are my elder brother..
I will speak as per my understanding here.. but generally, the concept is well understood among Muslims, and even other religions..
So there are religious duties which are between Allah and His creation.. such as Salah and Saum, and Hajj etc.. There are people who flog those who don't pray.. they are wrong.. TTP extremists were the best example of those extremists..
There are religious duties which are not only between Allah and His creation.. for example, how you will behave with your parents, with your wife, with you husband, with your neighbors, with animals etc.. So if someone stops paying Zakat, it is Islamic states responsibility to force him to pay.. If someone starts abusing his animals, it is society's responsibility to condemn him..
Now the third one.. where Allah has ordered to do something.. for example, how to dress modestly, punishing adultery (remember that there is a requirement of four witnesses for a reason), etc.. that's what one's personal as well as Islamic society's matter... why? Because if someone comes out wearing objectionable cloths in front of my family, I have a right to ask the state to force him to dress appropriately.. But, I am no one if he does that inside his home.. Similarly, if someone is doing adultery, and he is not seen by many (four witnesses seeing clearly what was happening), it is his personal matter, but when four witnesses see him, it becomes Islamic society's problem.. because he wasn't careful in keeping it personal..
So Islam has forbidden us to look what's happening inside someone else's house in the first place.. but if someone is doing it openly, so much that four people can clearly see the act, it means that he has started advertising this act.. tomorrow he can do it on a busy highway.. and then people may start taking lessons from him.. This is where it becomes the problem of an Islamic society..
