I dunno, I don't really see her caste status as a big factor in her political rise/career. Also, she's not really the "settler" since she was born here right? It would be her parents that are the "settlers"? But wouldn't "immigrants" be more appropriate for her parents? It's not like they came here to dispossess the natives of anything. I think you're really stretching your analysis here with both the "Brahmin" and "settler" thing. She's bad, but not because of those reasons.
