I disagree with the Modi and Hindutva project almost entirely, not only politically, but on a personal level coming from a minority community (Christian) in India. However, India is in what basically amounts to a perpetual state of war with Pakistan and has always been this way. India rarely agresses Pakistan and Pakistani terror groups do operate with seeming impunity in India (Pakistan doesn't even maintain a 'no-first-use' nuclear option, and is currently run by a military dictatorship... they're f'ing nuts). While all these actions are obviously crazy and in my opinion overbearing, people in the West don't understand how awful radical Islam is, especially of the South Asian variety. I'm not sure many Americans would react differently to the extremism of South Asian Islam to be honest.
To put it in perspective, many Indians (of all religions) died and fought in a bloody war to secure Bangladesh's (then East Pakistan's) freedom from what was a genocidal regime in West Pakistan. Decades later, the typical Bangladeshi muslim still hates Indians because any non-muslim Indian they consider 'Hindu', thus polytheist, and thus worthy of death. One thousand five hundred Indian soldiers died only for their neighbor to hate them in return for the 'crime' of not being born part of their religion. While Hindu nationalists are fucking insane, I honestly think many have been driven to it by the insanity of South Asian Islam.
Meanwhile, America has a relatively peaceful and cooperative neighbor (Mexico), which only has a crime problem on the border, and the average American seems ready to give up almost every civic right to deal with that. There are barely any terror attacks of note coming from these Mexican gangs, and congress has already ceded many constitutional rights (such as the right against unreasonable search and seizure) near the border zones. Anyway, imagine Mexicans hated everyone in America for the crime of being 'gringos' (even the non-whites) and that's basically what India has with all their neighbors.
If people in the west want India to liberalize, which we really should want to do, Western nations need to work on dismantling Pakistan and limiting Islamic extremism in the region.
