I have just begun to notice, but I have no idea about the identity politics. I recall in college that some of my friends from India would fawn over certain last names, and I felt it was something to do with the caste system, but I had concluded that the people I was around in universities and in the workforce were mostly from a level of privilege that it wouldn't be possible to learn more. I always found Indian nationalism to be strange, where so many people would interject that everything is perfect. Makes it easier for me to avoid my own US nationalism, because it must be just as comical to others.
In this article it mentions Dalit. How many people from that group would be in Silicon Valley, is it impossible to know since it is insensitive to ask and disastrous for them if people did know?
Seems like there is a potential for solidarity amongst more vocal groups pushing for representation.
