It's an "Open Letter", more of an invitation to discuss. It's intended for a larger audience because doors are closed within the hierarchy of the scientific field where scientists can talk science till their hearts content.
If it was purely science based, Dr Embry has a website to publish on but talking to a facebook audience is hardly the place for a scientific discussion although a few scientists will read.
Peer pressure has a part to play as many patients are beginning to think the medical hierarchy are snorting superglue
"of the 12,000+ patients treated so far, over 90% have had undoubted CCSVI."
If I was to be picky I'd ask Dr Embry to rephrase the above statement as there seems to be much confusion over actual figures. It doesn't really detract from the point but I don’t think anyone is sure of the numbers, so it might appear sensationalism.
I don't know Dr Freedman's views on superglue but from what I understand he clearly focuses on chemicals. Dr Embry stated his concerns on the lack of support for Vitamin D, etc, backed strongly by science. Much of his 42 years revolves around vascular health.
Call it serendipity if you want but Dr Embry has an educated opinion, and much can be backed with solid scientific theory. Dr Freedman is making bizarre statements on a regular basis, possibly backed by superglue or some other chemical ideology, that lacks sound scientific proof. I think Dr Embry is asking him why & just hoping to further the conversation scientifically or asking him to shut his gub.
Science goes round in circles & it sure as hell hasn't come close to fixing MS (quite the opposite). Personally, I rate Dr Embry's contribution to CCSVI higher than Dr Freedman's but like the rest of this post, just an observation.
I question Dr Freedman's motives for his outbursts in the media. I question his logic & reasoning. I question his ability to represent those with MS impartially. I suggest Dr Freedman is avoiding issues with disinformation tactics, avoiding issues with his own variation of nonsense.
I advise Dr Embry to check over his information until there is no possibility of rebuff, facebook or otherwise because he knows nothing short of watertight will fly, unless it's a discussion on superglue.
