from the article: "On every single measure of mental health, mental health seems to get worse the more Leftist you are. And among the far Left, mental health is perilous. For example, Kirkegaard finds that 45% of “extremely liberal” females have “ever had a mental health problem” (as opposed around 18% for “extremely liberal” males). Among “liberal” females, this falls to just 15% and among “extremely conservative” females, it is less than 10%."
