While I agree with most of what you say in your article, I take exception to you ascribing blame for the attack on Hinduism on "hostile Indian-origin Marxists in America." There are Indian Marxists as well who attack Hinduism. One example is Romila Thapar. She is considered a great history scholar. Having read her treatment of Ashoka (the Great Mauryan Emperor) convinced me that not only she is not objective but downright hostile to Hinduism and India.
I would also include in the "usual suspects," some Americans of non-Indian origin - specifically this Sanskrit professor from Harvard - I forget his name.
Generally I have found this to be true: If you want to flourish in the West as an author (of fiction or non-fiction), targetting Hinduism is your best bet. I include Salman Rushdie, V. S. Naipal, A. Roy in this group -- all extremely popular in the West but the underlying message is Hinduism is bad.
