Today was a weird one for Justice Thomas. Along with his bizarre and confusing dissent in the Oracle/Google case, he has done another one of his random walks down conspiracy theory nonsense lane on an unbriefed issue in which he gets to, once again, attack the 1st Amendment. He's done this a few times now. Two years ago he did this in writing an unprovoked attack on the 1st Amendment regarding NY Times v. Sullivan. Last year, he did it with an unprovoked and bizarre attack on Section 230. And now he's done it again.

Today, the Supreme Court declined to hear an appeal on the Knight 1st Amendment Center case, in which both the District Court and the Appeals Court made it clear that when a government official, using social media in an official capacity, allows replies on a posting (such as a tweet), they are creating a public forum in that space, and therefore cannot engage in viewpoint discrimination -- including blocking individuals for speech they disagree with.
