I think my favourite part of the article is this:
"In fact, it is the arrogant scientific establishment which questions free expression. Think of the hoo-ha which occurred when one hospital doctor dared to question the wisdom of using the MMR vaccine.
The point here is not whether he was right or wrong - it was the way in which the scientific establishment closed ranks in order to assassinate him."
I love the subtext here that the author clearly was extremely concerned by the link between autism and the MMR vaccine (which nobody who actually knew anything about clinical trials was ever really concerned about), then once the person was proved wrong, changed his position to "It doesn't matter whether he was right or wrong, these things should be investigated anyway."
Of course, what he either fails to mention, or possibly fails to realize, is that the scientific community "closed ranks in order to assassinate him" not because they dismissed his claims out of hand, but because the paper didn't show anything about the vaccine or a possible link to autism, and the methods he used to do so were complete garbage. For example, he only examined cases in which the child's symptoms were thought to have started soon after receiving the vaccine, without any sort of examination of vaccine recipients in general (analysis of which, by the way, shows that there is no connection).
But the REAL issue was that it was dug up that this guy had received almost a million dollars from lawyers who were trying to show a dangerous link in order to sue the vaccine companies. This money was not only an enormous conflict of interest, but it came out of a legal aid fund intended to help the poor.
So basically, the author of this article is complaining that the scientific community is willing to point out when people are using bad methodology, and will expend a lot of effort to investigate and uncover any corruption in the system. Yeah, those are really bad policies if you want to benefit society.
And of course:
"There was a blanket denunciation of his heresy, just as there is if anyone dares to point out some of the mistakes made by that very fallible genius Charles Darwin."
Despite the fact that it's widely known in the scientific community that many of the ideas originally proposed by Darwin were incorrect, such as the mechanism for the acquisition of beneficial traits.
