I think the issue is that many personal and organised spiritual belief systems will inevitably make claims that cannot stand up to any scientific scrutiny. What may seem an outrageous claim to one person, may be a matter of faith to another. I'm sure many of us hold opinions on belief which are determined by personal experience, rather than through scientific validation (I'm always reminded of the fact that science could not explain how bees could fly, or fish swim as fast as they do, until more recent breakthroughs in modelling turbulence using chaos maths over the past decade - should we therefore have disbelieved that bees could fly or fish could swim fast before the maths was able to explain?). In terms of racism - I agree that initially I raised the question of connections to the Neo Nazi's with Theosophy - but at present I'm satisfied that while there may have been anti-semitic beliefs held by people such as M. Blavatsky, I don't see this followed through in the Theosophical writings or philosophy since. I mean, if the TS really were focused on white superiority, why would they have announced the world's messiah was the Indian Krishnamurti in the early 20th century?
