I'm not sure why people who have been harmed speaking publicly about that in an open forum is "an echo chamber"? In fact, in my experience both as a writer and as a reader, and as noted in this OP, what it typically gains one is further abuse. So, sure, let's have some real dialogue, but that has to entail the person who has no firsthand experience with something shutting up and listening, and accepting that the speaker has some sense of their own experience and emotions around it. What I see instead is a lot of telling people that "It's not so bad" and "this is how you should handle it" which is completely antithetical to actual dialogue. It's condescending in the extreme and entirely paternalistic. This is not an intellectual exercise for marginalized people - this is their deepest most visceral pain - and wagging a finger and telling them they ought to handle their lifetime of abuse in a more sensible way isn't helping.

In my IRL job I am a life coach. You know how I get people to see the places where they need to change or where they are standing in their own way? I validate where they are right now. I meet them at the place that they are at today and make them feel seen, heard, and cared about. Only within that safe space can we begin to tease out the places where they might want to do something differently - because they can see it for themselves, and not because I told them they should.

Trust has to be earned. And it's earned in large part by listening and not jumping right to "You're doing it wrong, you shouldn't feel that way, you should be focused on other people's problems as well..." - particularly when those are coming from the demographic that has historically abused you. That's not "equal" dialogue - that's further abuse. Certainly, the other person can ask questions but this place of judgement and tone deaf finger wagging of somebody else's personal lifelong experiences is not acceptable to me, and it’s also never going to move the ball. If you care about things getting better, and I believe that you do, it’s not going to be accomplished by standing on a nearby hill and judging someone else’s pain.
