I am once again forced to question the cultures of Adab and politeness. When people don’t tell you what they are feeling and thinking it often leads to bad communication and increased conflict. So neither the”always be polite” nor the”say it all like it is” mottos work universally. Each situation needs to be assessed on its own merits and specificities. The ”one size fits all” reflexes simply don’t work in the world of reality!
Point of evidence. Look at one of the great cultures of “adab”- the Arabic culture. There is more conflict in that area of the world than almost anywhere else! Point taken!
