Bigotry and racism exist are remnants of the evolutionary imperative of genetic competition, it's hardwired back to bacteria.

Race is mostly a powerful social construct. It's can be used interchangeably with ethnicity in some cases. From a biological perspective, definition of race is more fine grained into several different populations, which is getting more opaque as people move around. But it's not like those "populations" are so distinct that there are more genetic similarities within them than between others.
Black and Caucasian are the most easily discernible differences. Probably why it's the most easily assumed prejudice.
You are very wrong. The overwhelming majority of Indians are purely South Asian. Unless you want to go back thousands of years, because no one is purely anything then. Very very few are Anglo-Indian or Portuguese or whatever. It is simply that Indians are very diverse in their cultures & looks. And yes, it is a race, because race is a social construct. Black is a race, but African Americans range even more in their genetic makeup & look than South Asians. This also is not true, though a commonly held belief. There is a lot more overlap than that, as there is everywhere in the world. North Indians are (very generally) lighter, but that's all you can really say.
Eventually humans will have very similar features (gray skin, big heads, large eyes, narrow frames, spindly limbs).
