The last four and a half years present a master example in a key phenomenon related to truth during political conflict: when swords and knives come out, brains shut down. They must. You just want to survive. To do that, you destroy your opponents, without thought.
I used to think that efforts to restrict free speech in politics were fated to fail in the United States, ending in the same trash bin as socialism, communism, and free love in the Senate washroom. To propose ideas like regulation of speech was part of our free expression. You could criticize these proposals, but you could not object to their existence, or to their publication. You could only explain why they were bad ideas. When government officials propose bad ideas, however, you have to speak up, strongly and immediately.
Look where we have arrived. Indignant partisans demand that a few companies remove someone’s voice, and the companies comply! The companies can remove unpopular platforms, such as Parler, or unpopular individuals, such as the former president. They can remove people’s ability to communicate in the present and future, and they can wipe the record of all past communications. That is not the freedom we contemplated, or anticipated forty years ago.
