Meera Nanda tells you why she criticizes Hinduism:

Like Manoj and other Indian rationalists, I have often been chided by fellow Indians – fairly mainstream, middle-class bhadralok, most of them — for picking on Hinduism.  I am asked if I am so concerned about irrationalities and pseudo-sciences, why don’t I take on Islam and Christianity?  Aren’t they full of faith-based nonsense? Hinduism, my critics tell me, is far more rational and “scientific” than these other “Semitic” religions in which you have to take the revelation purely on faith, no questions asked. I am often told rather gleefully that all my labors are wasted because they I am not aiming my rationalism against Christians and Muslims.   Some go even further and assume that because I am critical of Hinduism, I must be a secret Christian, and I must be working for “the proselytizers”! Apparently, no one born a Hindu can legitimately raise questions about the “Eternal Truths” of the faith.
