I think the point I was making was obvious. You’re just being obtuse on purpose.
To spell it out:
Hexbear is going out of its way to avoid becoming an echo chamber by federating with liberal instances. Blocking Hexbear is obviously more echo chamber-like than allowing it, and opposing echo chambers is clearly a nonsense reason to defederate.
“Instance specifically set up to spread propaganda”?
You’re just talking out of your ass. Hexbear has been active for years. It was set up as a lifeboat for /r/chapotraphouse.
What happened to “defederating should always be a last resort”?
Hexbear is probably the most inclusive major instance. We’re the only instance with mandatory pronoun tags. And yet we get defederated before we have a chance, while Exploding-Heads got to stay federated for so long? Our admins even went out of their way to make things easy for you, too. Did you even talk to them?
