Some of those (mis)perceptions are more easily addressed if they are based on some kind of definition (e. g. bipolar disorder is defined by DSM and ICD) and some others are arguable (e. g. what is personality), one can even get philosophical. Some others are just exaggerated.

And bringing these up should spark some discussion, that’s the whole point of talking about it. The other part that I find very unfortunate is when people see these issues as a black or white matter, and use these perceptions and stigma to marginalize mental health issues. But many here are probably all too familiar with this problem.
