@PM,many indians may not have come across/experienced casteism firsthand in daily life themselves simply bcos of where in India they grew up,but it is something that has been taught to us as an evil even in our school/ curriculum growing up..Its a practice thats been banned officially..Its just that old traditions take time to die out and many people even today esp in rural/remote villages are prone to be victims of exploitation due to this..I dont think any Indian ever denies its existence,just that they may be speaking from their own experiences of not going thru/following it themselves...
