Wow. Why does this not completely surprise me?
Big events like this take place in many of our cities across the nation at various times of the year (well, mostly summer) and of course they cause disruption to the immediate area where the event is being held, whether it be noise, traffic re-routing and of course the influx of people attending the event.
There is no way that any governing group should consider cancelling events because a minority group "disapproves" for whatever reason.
