Thanks for your reply. In recent months, I've moved away from writing direct thesis statements, or even from writing with a particular thesis in mind. My goal isn't really to make an argument, but to paint a picture of a landscape of experience.
If you'd like a TL;DR, this is my best attempt: pollution is a form of trauma, and trauma is kind of pollution. Disposability culture leads to the proliferation of both, and atrophies our capacity for healing. Again, in the case of overt abuse, being able to exit a relationship at will can be life-saving, of course. And I'm grateful that culture is at last making room to talk openly and publicly about abuses that so often get ignored because they happen in private and we considered them taboo to discuss.
But for so many of us, we end up profoundly traumatized by things that aren't necessarily abuse, experiences where the roles of victim and perpetrator aren't so clear and it's hazy where the line is between what's acceptable and what's not. The more we atomize our relationships, the less we have the chance to heal them. The more we scratch our itches with commodified coping mechanisms, the less inclination we have to heal. And we need to heal, because all our unhealed trauma is spreading and toxifying the whole culture. We don't want to date people with unhealed trauma who project it onto us, we don't want to be people with unhealed trauma who project it onto others, but we don't know how to fix ourselves when the problem is so endemic and it's so easy not to heal.
Nothing gets broken down by a single organism; remediation takes an ecosystem. I don't know how we culturally remediate our relationship trauma, but I know we need to, and that the job is a cultural one.
That's just a shorter version of the essay. Again, I can't say exactly what the point is, beyond telling that story and pointing towards a certain way of looking at the problem and the possible solutions to it.
