I'm not saying "no true Scotsman." I'm saying Mussolini was a legitimate fascist, and his party died a long time ago. Some people today have similar traits, especially on the Left, but nobody is really part of his party anymore.
Free speech is a delicate principle. It requires everyone to firmly agree that everyone is allowed to speak freely, and we're all prepared to fight to the death, literally, to defend their right to say it. It's delicate because as soon as people abandon it, the entire project of western civilization can be destabilized. What we are permitted to say on kbin and every other online platform is the essence of free speech.
