A friend pointed out that I give an impression that the people I work with are not only consistently liberal, but have an extremist streak. He knows from experience that this is not so. He is right, and I should correct that impression. I will include an anecdote, to keep it memorable.
Social workers are largely liberal, and a few are pretty extremist, but there are two interesting points. Some have a pretty strong sense that "your decisions have contributed to this, and I don't feel obligated to rescue you from everything." A significant minority also came into the field from religious, helping-mankind, or personal addiction 12-Step perspectives and have something of an accountability streak.
This is not so for psychologists and OT/RT sorts. They are almost thoroughly liberal. Psych nurses are mixed, and I don't have a neat categorisation of how that is. Married/unmarried/divorced, young/middle/old - I don't see patterns. Mental health lawyers are very liberal, hospital administrators are as well (except for the accounting and budget guys. No surprise there.)
Psychiatrists are quite interesting. Most are pretty liberal, especially politically - but that accountability question comes up a lot and they back off from the extremes. In my experience, the female psychiatrists are more conservative than the male. The anecdote: a female psychiatrist with a young daughter was talking about some Disney Princess experience they had been sharing recently. Because my granddaughters are deeply involved in several, I was chiming in a bit talking about art, myth, values communicated. I see good and bad in the princesses. Another woman present expressed the reflexive disdain that educated feminist women are supposed to have for princesses - and threw in Barbie as well. The psychiatrist smiled slightly, not commenting. After the other left she sighed, then twinkled. "I loved Barbie and dress up my whole childhood. I decided after I got my master's in organic chemistry and got accepted to med school that I didn't have to answer to Women's Studies majors anymore."
