I would say it's only a matter of time before someone on Era kills someone in a moment of political violence, but it's not like it matters. The internet at large is getting more open to that in general, right and left. This is likely to be the norm going forward, and keeping track of it will be a fool's errand, whether it be big platforms like Twitter and Facebook, or niche communities that have been radicalized like Era or Somethingawful.
