@aral Gargron seems to believe very little of the hate speech will spill over here (says they've only had 68 reports of posts from Threads so far) and that they can deal with moderating it.
He's overlooking (possibly intentionally) the double standard where explicitly pro-hate-speech instances are normally defederated on the basis of intent not action, and that now that Threads is an explicitly pro-hate-speech instance, it's somehow not being treated the same way.
He's also overlooking how folks replying to hate speech to argue against it will result in it getting federated and put in front of people.
