Your initial message suggested “it’s time to defederate”. It definitely came across as you being unwilling to discuss “viable solutions” and wanting to jump straight to the nuclear option. As the OP mentioned, getting Blahaj defederated is probably the ultimate goal of this user, and user’s like them. I think you got a pretty reasonable response, all things considered. You don’t get to dial the heat up to 11 and then get upset when people respond in kind.
