The worst stuff I have seen has been though Facebook, I haven't head anyone IRL saying racist shit towards the travellers, the worse I have heard has been that they are making a mess, and they shouldn't be there, but then, if there was proper provision for travellers, then they wouldn't be resorting to squatting Lancaster Uni's rugby pitch. Also the only thing I can see LUSU doing is putting a statement in SCAN, our student newspaper, regarding this, and it will probably contain some errors as well, they aren't known for their revolutionary left-wing attitude.
However, several "Autonomous University of Lancaster" (local anarchists and hippies) have written in e-mails to the University authorities criticising the University for stirring up a "them and us" meantalitiy between the Travellers and students by saying "we are trying to get them removed" and advising students "not to approach the travellers".
