Venting is a common concept in American English.
It is a metaphorical word connoting other metaphors with similar meanings: blowing off steam, getting something off your chest, getting something out, getting it out there, clearing the air, etc.
I think it would be much better if we greatly demoted these small metaphors and replaced them with plain speech, such as: I want to speak about something with you and hope you will listen to me and provide some feedback.
Speech is sacred. Speaking honestly to someone who listens honestly is always transformative. Our common metaphors for needing or wanting to speak with someone too often obscure the beauty and profound potential of these important speech acts.
Another distantly related point to this is all the deconstructing going on right now in American society.
What I want to say to you about this is simply: any technique used to deconstruct America can very easily be used against any society anywhere in the world during any period of time.
All groups can be deconstructed easily because all groups are fundamentally simple. They are lowest-common-denominator communication systems shared by their members.
A little deconstructing and intelligent analyzing can be good, but too much is destructive. It’s much easier to destroy something than build it. And building new or better things does not always mean destroying established things first; in fact that approach rarely works.
