Andries,
Your asessment of 'not very harmful' seems rather pedantic - it's a bit like saying a cliff is only dangerous to those who fall over it.
When talking about harm or danger, particularly if one is considering a wider societal perspective then one must give some thought to the 'cautionary principle' - that is a 'danger' that is potential is a 'danger' that is likely to be made actual. Rawatism may not present a threat to large numbers of people- but the harm that it can do to individuals can be catastrophic.
On the scale of human harms Rawat comes a long way below SARS and AIDS and Climate Change - but this forum and ex premies in general are not expert in SARS or AIDS or Climate Change - we are expert in the world of and harm caused by Prem Rawat. One of things we can do is put up a sign saying 'watch out for the drop'.
