In my opinion, the people who think the Large Hadron Collider will destroy the Earth are the same sort of people who don't want permanent Daylight Saving time for summer here in Western Australia (we're about to start year 3 of a 3 year trial) because they think it fades the curtains and makes the paint on the house fade/peel faster, etc.
And, believe me, there's quite a lot of them here.
