From your posts below, it seems you accept that we have a right (and maybe a duty) to discuss facts about Rawat and those who publicly defend him. Clearly this is difficult for those who have friendships with those people, but that doesn't mean we can't discuss them. Your London Underground example, though, is totally inappropriate because as a consequence of working for them you became aware of facts that the general public weren't aware of, and that changed your view of their performance. If those facts you became aware of were in the public interest, then it was your duty to share them. Glen Whittaker is aware of facts about Prem Rawat that the general public isn't aware of, and it his duty to share those facts, not lie to hide them. If he was my friend I would tell him this, although I accept he would be unlikely to remain my friend aferwards.
