Obvious as it may sound, people with authoritarian beliefs hiding behind free speech actually consider it as a weakness akin empathy. It allows losers like them to amplify their reach despite not being in power. They abandon their “free speech absolutist” postures the moment they think they are in power.
This is what the fascists do: hijacking legitimate terms of discourse and abusing them so they become meaningless. It’s a deliberate strategy to subvert their opponents’ ability to talk about the issue by poisoning the terminology. See also what they’ve done with “fake news”, “critical race theory” and “DEI”.
