Some of the stuff on here is ridiculous... I seen someone post on the first page there than 'UKIP are bad because they want to take human rights away from the UK' as if leaving the EU and their human rights legislation would mean no human rights and terror for Britain. Pathetic.
That said, whilst I do like Farage, some of UKIPs policies need going over! Bad? No. Room for massive improvement? Yes.
Overall they're a good thing, they've got the public's attention, people are engaging with politics again, and the rest of the establishment is forced in to answering difficult questions/dealing with difficult issues they would be only too happy to ignore otherwise.
