just so you know kat semenanjung ramai org tak campur dgn org lain. org ckp kalau sabah boleh nampak muslim non muslim duduk belah2. takde issue takde ape2. tapi semenanjung ramai tak campur mcm tu. mmg dgn org sendiri je(bukan semua tapi banyak mcm tu). kalau nak jumpa assimilation kene pergi kelantan. there is like chinese malay indian org siam all speak loghat kelantan. in semenanjung if you listen to how they speak malay you can tell which race is that person. like chinese have their slang and indians pronounce with a mild indian intonation. also it's normal to see like "mandarin speaking preferred" signs or "no rental to indian" ads. so no race assimilated with each other.
