When I read posts on reddit about crazy Americans, since I live in the U.S they don't shape my perception of the country (rightfully so). When I read a post about something crazy a guy in China did, I make inferences about the country and culture as a whole - and so does most of Reddit. I'm a bigot.

Think about it. Two different posts:

"Chinese man leaves baby for dead on street of Beijing"

Top Comments - China is fucked up, their culture is about self preservation, it's the result of China's corrupted insurance system,

"Florida man leaves baby for dead in Orlando"

Top Comments - What a terrible person, he deserves to burn in hell, the world is fucked up, how can such people exist, lol florida man! at it again
