Why do believers obey some verses to the letter and quietly ignore others?
Leviticus bans gay sex (18:22) — three verses later it bans eating shellfish and wearing mixed fabrics. The Quran's rules on inheritance get followed; its rules on slavery get 'contextualized'. Everyone is a cafeteria believer; they just argue about the menu. So who decides which verses are eternal law and which were 'for that time'? Pick a side.
