The new issue of Shift magazine has an interesting article on Indymedia and anti-semitism.
Put simply, the usual open door posting policy on Indymedia UK is a green light to all manner of fruitloops to post any old nonsense.
The 9/11 'truth' movement must take a large share of the blame for this. Many of the nuttier and more unpleasant posts to be found on Indymedia originate either from 9/11 truth activists, or emerge from their wider milieu where blaming Israel and/or 'Zionists' for all of the world's ill's is part of the daily routine.
Bristol Indymedia has previously hit choppy waters due to the conduct of Tony Gosling, one of the best known UK 9/11 'truth' activists. Just as that particular Indymedia group was better off without the dead weight of Gosling's prejudices around its neck, so Indymedia internationally needs to firmly dump the 9/11 'truth movement'.
Should they do so, they will find their problem with anti-semites is seriously reduced.
