Dissociating yourself from people based on their beliefs is new thing and it's wreaking havoc. The colleague in question did not even ask any details about author's faith and what was told was enough for him to disassociate. In this case the author was treated like lower caste Indian. The proper negative response would be in my opinion "I don't like discussing religion, can we keep it outside of the conversation?"
