Is there nothing that people won't just believe?
It just depends on where you look. There are lots of people who question and try to bring good things to the country. One could ask this question about almost any country Brazil for example.
“having or showing too great a readiness to believe things” May be.. Was talking with a woman today describing her ‘good christian sister’ (think I’ve a new, if married, atheist friend) as ready and willing to believe anything! It’s like ‘we’ choose our desired truths, then seek sources promoting it
Gullible public. I don't know how clueless people are in other countries. I assume there's billions of idiots on this planet.
Idiocy is not the sole prerogative of the (dis)United States of America. You will also find it in South America, much of Africa, significant parts of Europe, much of the Middle East, and also in the Land of the Convict.
