Maybe Brahminical forces are opposed to healthy discussions.
But are you aware that it was Brahmins who used to have detailed discussions and public debates about different philosophies?
Do you know that Savarkar, founder of Hindutva, was an atheist?
You see, atheism is against western religion, because western religion means compulsory belief in inerrant dogmas that you are not allowed to question. That has never been the eastern understanding of religion. Atheism is as much a part of Hinduism as theism is.
