Your cynical attitude about psychologists and psychiatrists proves my point: some behavior is just rude, NOT a sign of mental illness. Therefore it is inappropriate for anyone - esp. a non-doctor who has no business handing out diagnoses but is still read by thousands of people and must command a degree of respect from some of them - to say someone has a personality disorder. Doing so reinforces stereotypes amongst people who don't know any better; contributes to the medicalisation of society; and underplays the suffering that people involved with mental illness actually face (that includes patients' loved ones).

And you know, most of us are actually in it to help people, not to pay off student loans. Psychology isn't as well-renumerated as medicine: you do it for love, not money. So f*ck off.
