If you're wondering why marginalized people on social media seem constantly exasperated with the folks in their mentions, remember this:
At a town hall meeting, it's obvious when one person is hogging the one mic, interrupting the current speaker, and generally being a nuisance. It's also possible to peer pressure them into shutting up or not returning.
On social media, one person can waste the time and energy of dozens of people at scale, in private, while maintaining a polite facade.
