Americas has a huge problem. I think calling it mentall illness has done a grave disservice to hunanity. It means that people who are mad and should not be allowed a voice in serious decision making are given a voice.
And when there is something as dangeorus as climate change, then you understand that they could be the death of us.
You don't give a dangerous weapon to someone unskilled in using it, and you don't give decision making powers to people who aren't educated enough to make correct decisions.
