Maybe it is because they have spent time in the US that they want such women?
I would be willing to give the benefit of the doubt to somebody who has lived in a conservative, patriarchal, rural/small-town middle class environment in India.
If you are an Indian male in the US as described in the article, chances are you come from an urban background, went to college, and have had ample opportunity to be exposed to more liberal attitudes. In that case, this sort of expectation is downright shameful and disgusting.
