man, i'm sorry, but your stretch your personal unfortunate experience too far. Such broad statements require good links. I already posted this in the other place : http://nccam.nih.gov/health/chiropractic/introduction.htm
On the other hand, problems with the practice are widely documented: http://www.theguardian.com/lifeandstyle/2012/may/14/dangers-...
that is outright fantasy.
"NIH is made up of 27 Institutes and Centers, each with a specific research agenda, often focusing on particular diseases or body systems."
My experience with a specific NIH's center - NCBI - and their work clearly correlates with it, they [ ie. their own researchers] are doing fundamental science.
The rest of your statements goes the same way.
