It only takes a tiny spark to set a forest of dry tinder ablaze. You are right to be angry - it's meaningless. What's more important is that you have firefighters ready and trained to stop the fire in its tracks.
What's positive is the outpouring of solidarity, particulary among white Brits who have no intention of living on top of a bonfire and value diversity. Its important that we both appreciate the seriousness of the threats and remain hopeful. Hope is a fire retardant.
