Incredibly, incredibly rarely. The demonization of mental illness and testing everyone who's mentally ill, whether they're suffering from Major Depressive Disorder, Bipolar Disorder, Borderline Personality Disorder it what have you exactly the samethat is, like they have Antisocial Personality Disorder and are completely dangerous, insane, violent but jobs who could hurt anyone and everyone around them at any timedespute the actual facts and data in ABSOLUTELY NO WAY baring this out (in fact, consistently showing to the contrary-that they're more dangerous to themselves than anyone else) is one of the huge problems in this country that lets stuff like this happen.
People are very, very poorly educated about mental illness here letting incorrect and dangerous stereotypes and misinformation fill in the blanks, leading to the mentally ill being unfairly stigmatized and portrayed as a threat and it's one of the topics that infinitely infuriates me and I won't stand for people contributing to that stigmatization, intentionally or otherwise, as done here.
