I didn't even check the source of those numbers; it was just the first thing that came up in a very quick search. It doesn't really matter: even with 500 million or 100 million you've got the same "a small percentage of a very large group can cause a lot of havoc"-effect. You see the same if you drive to work: you can easily encounter over a 100 of other drivers, and only a very small percentage of them can give the perception that "people are such bad drivers" when in fact it's just the 1% of the 100 people you encountered on that trip.

I find it both depressing and comforting; it's comforting to know most people aren't that bad, and it's depressing that such a small group of assholes can fuck it all up.
