Serious answer: my guess is that it's because the Indians that have the means to immigrate tend to be the upper-caste types. The fact that a lot of them immigrate on small-business/investment visas (self-selecting for "rugged individualists") only enhances that.
It's similar to the reason why Cuban-Americans are often right-wing: they're the ones who fled when Castro took over, while the leftist ones stayed in Cuba.
not only do they self-select for "rugged individualists", but there's another layer of filtering upon entry into politics. There's a special kind of arrogance it takes to look at big, complex, thorny problems that arise in politics and go "I can fix it". That and tech bros are the new finance bros, so used to being lauded in their space that they just wander into other spaces and assume that they're already well-regarded experts and that the reason those areas still have unsolved problems is just that no one has thought about the solutions hard enough yet.
Are they, though? Far as I can tell, it's just this freak and Dinesh D'Souza. Not that they aren't both truly loathsome lunatics, but that's just two amongst millions of chuds, hundreds to thousands of publicly prominent ones..
