Wouldn't someone talking to someone "lower" on the "oppression hierarchy" just be what we basically have today? That sounds like "privilege," or an "imbalanced power dynamic." I think you'll only be able to talk to equals, whatever that is, and by whatever metric is en vogue for that day.
You’d generally only talk candidly to those who were not just peers, but you already had a deep seated existing rapport with and trust. Friends?
Everyone else gets the politically safe story that is supposed to be told. I’ve seen it in action, and it makes me sad because it becomes fundamentally corrosive.
And if you think for some people that doesn’t include the right kind of outrage discussion or telling the right stories to the visible oppressed minority they’re mentoring so they can get the right checkbox when they hopefully get considered for SVP (or as plan B, their mentee does) - I’ve also got a bridge to sell you.
