I saw the deleted post. It was measured & kind to the poster mentioned. There was a link to an Australian Rationalist Society article expressing a complex analysis & interpretation of Steiner education in that country, where public money is involved. Such analysis is to be expected in a democracy.
I could see nothing libelous in it or anything that could connect mumsnet to its views, any more than a link to someone's favourite song would be a thumbs up to talent.
If we believe in freedom of information we should allow adults to read material like this & make up their own minds, unless we believe them incapable. My brief experience of mumsnet reassures me that's far from the case! People can't make informed choices about something as serious as education when they are not allowed to read differing opinions. When government funding for Steiner schools may well be increased in the UK in the near future, this suppression of information due to a real or perceived threat becomes a matter of public concern.
Today Richard Dawkins spoke at the Libdem conference about the need to repeal the UK's libel laws. Such a thing is overdue, as those following the Simon Singh case know well and this is a link to a description of that case & is in no way itself libelous!
It's clear from the Quackometer article that it isn't just science that's effected: 'Free speech is reduced to a meaningless freedom as long as it does not effect business interests, political ambitions and dogmatic beliefs.'
This is serious. And sadly not irrelevant to this thread.
'It is time for a change. It is time for us to be free from fear when voicing our concerns.'
