On their website, the British Centre for Science Education claims to be a "newly formed organisation with the primary purpose of stopping the teaching of Creationism in UK state schools." They've had a letter published in the Times, and has even been endorsed by a motion in the House of Commons.
However, David Anderson at "The BCSE Revealed" has been doing some digging, and has discovered some interesting facts. For example, the BCSE isn't "newly formed". It previously existed under the name "Black Shadow", but changed to the current name earlier this year.
Their old website is still accessible, and invites people to "Join The Fight" by joining the British Humanist Association. The group is also using its concern about creationism in schools as an excuse to make political jabs at UK's Prime Minister Tony Blair:
It is becoming increasingly obvious that the UK government under the leadership of Tony Blair has an unstated agenda to increase the influence & involvement of religious organisations in the running of our society. Many of these are associated with creationism & other forms of fundamentalism that seem to have crawled straight out of the Dark Ages.
So, it's a group using concern for science as a front for its metaphysical and political agenda. Isn't that what many critics are accusing the Discovery Institute of doing?
