> Constantly being assailed like that takes its toll, and can lead to those people withdrawing from social media, removing their point of view from the discourse, and emboldening that of the bigots.
From my understanding of social media, it hasn't been workable trying to stop outright racist comments being hurled at those marginalized people -- so I just can't agree that not actually addressing the cause so we don't hypothetically do less damage than is actually being done right now by the problem is a workable idea. That's the kind of squeamish bargaining done by people without the stomach to tackle complex or hard topics: "Can't we all just get along without it being messy!"
Your complaint is like saying that surgery hurts, can't we just let the infection fester? The surgery doesn't even hurt as much as the infection! Why would we do that?
This is, for the moment, setting aside that we could work with technology to do better at time/place of those questions and filtering so the stream isn't overwhelming for (or even involuntarily sent to) any particular marginalized person. And so at a technical level, you're solving the problem in an inefficient way (trying to legislate human nature versus changing how we route text online).
