Considering a scenario in which parents ask/demand to stick to culture/practises (incl inlaws stuff) which at times are contrary to Islamic principles, would like to know-– shall we stay mum and stay patient with parents wrong doings?– or can we politely and respectfully discuss and explain that the wrong doings/acts are not compatible with Islam?– or is there a third option?Humbly request your guidance.

The second option is the best.
