Defederation should always be an extreme measure. Usually it's just the self-righteousness instinct trying to performatively obstruct other people. I usually find these discussions repulsive because of how people speak about each other (bitching about "tankies" or whatever and demanding that they be ideologically cleansed).
If we have more power to curate our own feeds, then there should be less defederation.
Enjoy your feelings of hatred then, I guess. Don't worry though, defederation will win and you'll be safe inside your silo bitching about how there were once people who said things you disagreed with whom you hated and continue to hate, and that hate is all you ever communicate.
