It is likely true that there is a high degree of self-selection here: because U.S. citizens dominate a lot of these discussion boards, U.S. news will dominate them as well. And because emotions garner upvotes, news of terrible things in America rise to the top. And on top of that, the most vocal, emotional commenters with the most amazing stories of U.S. suffering tend to rise to the top of the comments section.

Take it all with a huge grain of salt and stick to the facts and figures.
