I've been privileged to be able to attend the first hour-and-a-half or so of this. I've been privileged to be able to talk about the matter, and to scrutinise some of the issues, openly and freely. I've formed opinions (or had previously-formed opinions confirmed) on the basis of arguments forwarded in an atmosphere of open debate.
I've foregone the latter part of the evening, as I have work to do. But intelligent discussion and careful evidence-based scrutiny of claims continues, without fear of anyone being sued for libel.
Oh, unless you want to scrutinise certain alternative therapies.
