Shiv Viswanath writes in The Hindu

” Worse, there is a split, where the Muslim is portrayed as a butcher in these Hindutva dreams, while the cow as animal acquires a humanity. With this inversion, the cow becomes a person while the Muslim becomes a non-person, losing his rights as a citizen. Such a militant Hindutva has little sense of Hinduism or the Constitution.”

I agree with his view that Hindutva forces consider Muslims as non persons, inferior to Cows.
I also agree that it is completely in opposite to the position of our Constitution.
But to say that such an attitude has nothing to do with Hinduism is wrong. It seems Shiv Viswanath has not read Hindu scriptures properly. Or he is trying to absolve religion of its guilt , a very common practice among intellectuals to remain popular.

See Manu smrithi 4:162
“Let him never offend the teacher who initiated him, nor him who explained the Veda, nor his father and mother, nor (any other) Guru, nor cows, nor Brahmanas, nor any men performing austerities.”
Hindus always had a rigid hierarchy in which those without a sacred thread had much inferior position than the cows.

Hindutva forces are only using those inhuman scriptures to create hate and grab power.
