First of all and very for people like pagwatch, jute and others on this thread.
I'm a bit like you guys, I feel I have to come on these threads and present my child's reality in all this.
I don't want to turn this into a your guy's more of an asshole than my guy debate as very rightly pointed out by stuffitllama. I just want to answer slugs' question which is perfect reasonable.
So, concerning Martin J Walker. He is an investigative journalist who in recent times has written several books about the politics of the medical system. His most well known book is probably 'Dirty Medicine' but he has also written about HRT and AZT therapies. His books are well referenced and well researched and very interesting. He publishes his work through 'Slingshot Publications'.
You can read what he says about himself here.
You won't find him in Wikipedia because his page is currently deleted (if you click on the Wiki link on Walker's presentation page it will bring up the deleted Wiki page). He rocks a lot of boats and pisses a lot of powerful people off. There did used to be a page up about him describing him in rather unflattering terms. I bet there are a lot of people who wish he would just go away, a bit like his Wiki page .
He is also covering the GMC hearing of Drs Wakefield, Murch and Walker-Smith here.
He is neither a medical professional nor a scientist. His writing is political and investigative not scientific so I guess he is qualified to comment on these issues because he has 20 years experience in writing about the politics of the health system and even more as an investigative journalist. He has written (a little bit) about Goldacre because he writes extensively about pharma lobbies and health industry corruption and Goldacre is connected to this.
(BTW it would seem that part of the lobby's agenda is convincing the public that only medical people, like their man Goldacre, are 'qualified' to comment on medical matters. This is a blatant attempt on the right to freedom of speech. There is a whole lot on this but it would need a separate thread I think).
There is no particular reason for you to believe Walker other than he has written several well referenced books and that his essays and articles are always well referenced (and when you check his facts they are correct, unlike Goldacre's) . AFAIK he has yet to be sued for libel despite having taken on the big guys and their minions in an area of huge financial interest, so I'm guessing that what he writes must be true or somebody would have taken him out by now.
I first came across him when my DD1 was so ill we thought she wasn't going to make it and all of the dozens of doctors we saw about her condition failed to help us. I finally found a doctor who admitted that my child was probably vaccine damaged and who helped us to nurse her. When faced with my shock and incredularity about the covering up of vaccine damage he suggested that I read 'Dirty Medicine' in order to try and understand the politics of the health industry. I did, I was appalled.
