Generalizing everyone from a region/group with some negative trait is racisam.
If your brain try to label me as someone who practice caste system because you think I am from India is lazy/stupid computation and racism.
Actually vast majority of the Indians suffer from negative consequences of Castisam since they are supposed to be lower classes and society descrimated against them historically.
They want equality more than probably anyone you know of.
Indian constitution has done a lot for eliminating this. But there is a lot of cultural baggage that needs cleanup.
