Why? It'd just be a government sponsored 4chan. Do we then blame the government for having a platform that the next shooter is going to use to murder 50 or 100 people? What's the point of such a platform? Why would we waste government money on it just to have it filled with hate speech? Why would we, as the people who control the government want such a platform? If people want to publish in such a way, there is already a platform: the Internet. Start a website. Nothing prevents people from doing that. If they're too lazy, they can go to 4chan, etc. The rest of us shouldn't have to subsidize a cesspool of shit that has no positive uses.
