This is a very charitable reading of the comment, and the examples stated seem somewhat unrelated.
A closer analogy will be: "He was lost in New York City. Later, he cursed at all the Blacks who robbed him." Or "He had an intense negotiation with the financiers. He later cursed at all the Jews who were scamming him."
As you may note, the term "jews" or "blacks" or "Indians" (in the original comment) is not merely stated as an adjective to describe the individuals, rather it is used in pejorative sense to denote a cultural trait within the group that makes them act in a particular manner. A child comment by the original poster makes his prejudice quite clear: "Probably because Indians are the ones that are leaders in scamming? "
I get your whole point about talking about individual, subset, and group, but it looks like just a defence for calling Indians "world leaders in scamming.", rather than some data based, dispassionate description of the situation.
I wonder why it is necessary to mention "Indians that are scamming" him as if scamming is something only Indians do? Should I be careful only when dealing with Indian consultants and presume others won't lie or cheat?
If the money required "to design real (general purpose) multicore processors that deliver orders of magnitude better performance than what we have today" is in low millions of dollars and technical challenge isn't too daunting, why haven't VCs invested in such ventures?
I could respond to it but there is not much to be said. I think you have made my point.
