> What's mentioned in the article is that as caste is a primarily SE Asian phenomenon, this is a bill that targets SE Asians. People tend not to like being singled out on the basis of their race.

That seems weak.

One should not (and legally may not) discriminate on the basis of being Indian, which is a SE Asian phenomenon. One should not discriminate on the basis of having Native Hawaiian ancestry, which is a Hawaiian phenomenon. And one should not discriminate on the basis of how many of someone’s ancestors happen to have been slaves in America, which is an American phenomenon (although there are surely analogues elsewhere).
