It's a serious question. A racist party would not allow the likes of Haley, Scott, Jindal, Donalds, Salazar, etc.
What attracts them to the GOP? How the hell did Jindal win David Duke and Scalise's district? Simple question.
Plenty of South Asians are on the racist right (at least if they are of Hindu origin - maybe most of all if they are descended from the diaspora that the British used to run the empire and boss Africans about - like Pritti Patel or Suella Braverman).
In the end the right is mostly about class and money, even if race and sex comes into it as well (race being unusually prominent in a US context, it seems to me).
Just as working-class whites might be on the right because they primarily care about white supremacy above all else, rich dark-skinned guys will be there because it's all about a top-down class war for them, or because all they really care about is male dominance. And Hindu South Asians can very easily be racist against actual black people.
The Right is a coalition of people who got lucky in the lottery of birth and want to defend existing hierarchies and protect their privileges - they don't all have the same privileges in mind.
