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.
In that circumstance, I think it is clear that my sexual orientation is the basis by which they are judging the authoritativeness I have to speak on the topic. Never mind the formal qualifications, or the logic or veracity of what I am actually saying. Like, I know we all have little unconscious checklists like that for judging whether someone is credible, but it is uncomfortable to see the effect live.
Someone wants to disagree with whatever nonsense the hivemind is raving about in the moment, but in order to do so they have to prostrate themselves and make it clear whose side they're on before they make their (often very valid) point.
e.g. "I hate Trump just has much as the rest of you but..." or "Look we need to be super supportive of X group and my dad is actually X but..."
I've noticed this trend where people started to accuse each other of psychological trickery a lot. I think it descends as a "defense" from that. I was never really sure of how many psychological games were really being played and how much people just reached for the terms to use as dismissal from criticism.
