In the last couple of years, the science establishment in the UK have been getting politically active. a lot of this was started by the British Chiropractic Association deciding to sue Simon Singh for libel after he wrote that the organisation "happily promotes bogus treatments".
Although that complaint was eventually dropped (and as a result of the action complaints made against a quarter of registered UK chiropracters), the threat of libel still remains.
Is this some minor issue of concern only for the English and Welsh who are unable to open their mouths without considering whether they'll put their foot in it? No, for several reasons.
