Any country that has a plurality that believes a talking snake doomed the entire universe to damnation is the dumbest..
Nope - the US has a fine education system and turns out a lot of smart people.
You think ignorance about world affairs is more rampant in US than North Korea?
Here in Thailand, they teach very little of world history. Many people don't even know who Adolf Hitler was. Even the Thai history they teach is heavily revised. As for other subjects, they lean by rote and are taught to NEVER question your elders.
Which turns out some very ignorant, uneducated people. In fact, the brightest ones here are the ones that were sent to US/UK/Australia for an education.
So - this image - is pure trollery or simply ignorance of non-Western nations.
