Since at least 4chan, every uncensored public forum sheds leftist arguments within a year, or when the forum grows past low 100’s of thousands of users. Without severe moderation, socialist ideas collapse under the slightest scrutiny and retreat to heavily censored spaces.

Wrong. They live on in comedic, meme formulation. The ideas are immortalized even as we debase them.
It is the Nietzschean transubstantiation of values into pithy, cautionary tale.
