On the flip side of this of course you're conferring to yourself the power to judgement of validity of thought and experience, therefore positioning yourself as the arbiter of right or wrong, creating an imbalance of power between you and the said group.
To make things concrete, that a doctor smokes does not mean smoking is good for you, and if you're basing a positive account of smoking on the doctor's smoking, you're objectifying doctors as a whole, reducing their intellectual complexity to that of one of them that _you_ happen to find agreeable, therefore poising yourself above them all.
This, so much. It's also a way to diminish someone- to make yourself the arbiter of their experience and even the experience of their entire people.
One of the people I worked with in the past (some people may guess who) did this exact thing about me, and it's one of the reasons we don't work together anymore.
I've had trouble expressing in words how destructive and hateful this was. Your post is so important, I hope everyone reads it.
