I mean, conservatives in America are generally those who want to CONSERVE something they feel they have lost. Culture, Religious practice, traditional values etc etc. No, not all conservatives in America have to be white, but many usually are. They are afraid of change, sometimes for good reasons, and sometimes to their own detriment. Indian-Americans in prominent positions represent change. But it's not as simple as saying that White conservatives don't want Indian Americans or ethnics to become part of the "American-Experience". Ideally most conservatives would welcome minorities who fall in line with dominant Western cultural values. The problem is that today they don't even really know how to express what those values are, or what they believe in or even what their problems really are. For example, Cuckservatives will talk about all of these "bed rock issues" facing America, yet they will never mention anything honest about how Inceldom happens to men, or Cuckoldry, or their own worship of foids.
They also don't have the one back bone of Western society helping them anymore because, well, people stopped believing in it. Christianity was the backbone of Western cultural patterns. It's mostly gone, so there is only an echo of Christianity for the Cuckservatives to hold onto. For non-whites, it depends on their religious background as to how well they imitate and carry on Western traditions in thought and practice. Indian-Americans are mostly Hindus, and they really only started immigrating to the States in large numbers in the 1970s. They call it "the brain drain era" in India because supposedly all of the smart people from these developing countries wanted to study, work and live in America. Most of these immigrants were at one point or another seduced by the version of America the Leftists peddle, and in the last 30 years or so, it reached a fever pitch.
There are some Indian-Americans who vote Republican and when the country was seemingly more united I feel was more evenly split in terms of who Indian-Americans support. Many of them became social-liberals because they believed that the white liberal man is in their corner. This comes from the Clinton and Obama eras mostly, but the John F. Kennedy types really got it started.
Anyway, now days with all the chaos, I believe many Indian Americans will switch back IF they see what they think is a "respectable" conservative return to politics.
