Based on my observation from people around me, Indians tends to be more 'pious' compared to other races, regardless of their religion.

Of course. I dont mean all time talk religious stuff but for example this colleague of mine, she's a christian and never miss all those services etc. Her fb postings etc all Jesus related thing. Same with few my hindu staff. All if not most of them kaki rock like but sembahyang tak tinggal. 😅 Since we work 7 days, some of the days where they have to work got mintak cuti need to go to temple etc. Even muslims, generally I see indian muslims more pious that malay muslims. I'm talking abouy average joes that I know.
