Thank you for writing this. Echoes my thoughts but I never bothered to write it down. I participated in a 10 day retreat in California, and was also turned off by the pseudo-science and science-bashing. I almost started back on day 4, but stayed on because my friend who had come with me stayed on. In the end, I am glad I completed it. But the pseudo science bits left a bad taste in my mouth, and I couldn't continue with the practice. I think I learned a lot from the 10 day course, and may be I will try it again in future, though.
