Whole lot of stupid racist people whose brains were totally broken by having a black president for 8 years and Trump has done a great job of playing in to that and dividing the country further through lies and hate. So many people completely emboldened in their ignorance and vitriol.
It wont tell you the exact clashes obviously, but it will tell you if there's a super strong day like last year's Thursday.
last year we couldn't tell what will clash but everyone here understood from the beginning that most likely we wont be able to see all of Vampire Weekend, Pulp and Beth Gibbons
