“Sentimentality, the ostentatious parading of excessive and spurious emotion, is the mark of dishonesty...the wet eyes of the sentimentalist betray his aversion to experience, his fear of life, his arid heart; and it is always, therefore, the signal of secret and violent humanity, the mark of cruelty.”
-James Baldwin

There has been a lot of talk about vulnerability, the revealing of the self to the world rather than hiding. It strikes many people, including myself, as wise and courageous, because it is. What is not, though, is manipulation via the expression of vulnerability. That's drama.
I have seen so-called vulnerability used as a weapon. as a tool of avoidance and censure. Expressions of vulnerability fill up all the space, disallowing discussion. This is manipulation, not revelation. That is drama, not discussion.
