They will fanatically defend all Democrat positions and attack all Republican positions, which I personally believe is rooted in the majority of Indian Americans living there on temporary visas, since the Democrats are markedly more supportive of immigration than the Republicans.
I think it's well established outside the US (Commonwealth and Europe) that immigration and race aren't necessarily racial issues, with most Indians here feeling that immigration isn't the most helpful method to support other Indians or fight racial issues, with a focus on developing India economically being more helpful.
Versus Commonwealth/Europe, I also notice that Indian Americans don't tend to fight so much for day-to-day social issues that affect people in the community, such as homophobia. Exceptionally, Indian Americans don't poll high on polls for Islamophobia - though Muslims are mostly a foreign policy (or religious) issue there and the polls are more partisan.
