Imagine a White person, who is the head of the organization in a country sharing a post that African Americans are a "degenerate community". In any western country, the person would not only be promptly sacked, but would also become untouchable in mainstream organizations.
The Indian politics and judiciary have been compromised by right wing Hindu nationalists and it is impossible to expect anything from them. However, I expected better from Facebook. In a western country Facebook wouldn't think twice about firing any employee who shared such a post.
