I think the point raised here and by commentators like Dara 0 Briain is very important. The media are obsessed with balance, which for many issues is actually a very good thing - I would hope none of us would want a media channels offering political propaganda, rather than trying to present both sides of the story etc.
But the media also like to tell stories, and fulfill certain narratives. "Brave maverick Doctor takes on the vested and venal interests of the establishment" is a great story, one that appeals to many people who instinctively empathise with such a story.
And that is how Wakefield portrayed himself - then, and now - and his has built up a coterie of fanatical supporters who reject all the evidence which so thoroughly discredits him.
And portraying "balance" when it comes to scientific issues, particularly those to do with public health or even climate change and the like, can be dangerous. Humans are not especially good at weighing up risks and performing risk/benefit analyses, and if you see an issue being presented as a debate, with 2 talking heads offering diametrically opposite views, it is tempting to conclude that the truth lies somewhere in-between - but this is not always true.
The truth about the shape of the earth, for example, does not lie somewhere between "the earth is flat" or "the earth is round". One view is factually wrong, and so to present this issue in a manner as if suggesting their is a debate would be silly - but this is what the media continually do, when it comes to some of the big scientific issues.
There are other problems too - with the advent of the internet in particular, you will find people who believe they are experts in something purely because they have googled some search terms - that their internet search somehow equates to proper research, that opinions derived from such searchs can somehow be considered to be of equal import to an actual researcher -someone who has studies the topic extensively, attended University, performed experiments for years and years.
This superficial expertise also devalues the opinions of scientists to the general public, I think, and debases the "debate"...
