A celebrity says something and the internet overreacts. I'm shocked! Shocked!
I think the internet always waits in the wings, ready to overreact at the slightest provocation; or when there's nothing, it just makes it's own drama.
Justin Bieber signed the guest book at the Anne Frank House, and his words were harmless and were meant to be complimentary. What happens? The internet just explodes with indignation at how horrible and self absorbed this maladjusted young man is. Did you know about kids today? Yeah, get off my lawn.
