One of my better habits I've kept from my Twitter days is making it a point of following people from marginalized groups. This way, I probably have fewer delusions about this than most cishet white guys.
I am still sticking around here because I think the Fediverse is still the best chance we have of building better social media. But we do have our work cut out for us, and not pretending that the Fediverse is great for marginalized groups is the first step.
