I've got no issue with inventive or heated language. Adds a bit of colour and it's not like Matt Healey's on here getting upset that people are calling him a c**t.
I will say in fairness with Download though if you don't like the main headliner it does restrict your options as they play unnaposed except for maybe the Dogtooth stage. It's not like you can grab an alternative decent level headliner on tbe second stage. Glastonbury has much more opposite The 1975.
