That's because the shitty so-called NEWS media loves to splash this shit all over the place at every opportunity. Gets people riled up, gets viewers and site hits, etc. Guess what, there are no more of these types out there now percentage-wise than there were 50 years ago, you just didn't have the internet and mass-media around to spread it to every corner of the earth in hours.
I hate the media for contributing to this fear-mongering nearly as much as I hate those rare child molesters.
