I have the impression this does not necessarily apply to the US. There are plenty of examples of... vicious(?) fundamentalists that are rich and of the ethnic majority.
I guess what I'm saying is that your point is not mutually exclusive with the comment to which you're replying, and that extreme religious values can have multiple "purposes," explicit or implicit.
Rich hindus allways have means to do so with out resorting to fundementalism.
for example, ambani supported congress (which is anti-hindu), and when congress got weak, he started support BJP (which is pro-hindu). In both cases it is to protect his own interests.
Same is happening in US.
