I have discord for gaming communities, but also for political communities. Pod Save America has a discord with thousands of users talking political things. While I don't mask my identity there, I sure don't want Discord preemptively linking my state ID to my person. Screw that.
If you're worried about government retaliation they can already figure out who you are from what discord has, especially with a justice department that doesn't really even care about looking like they're following the law
