I don't think you understand how free speech works. Its literally the freedom to say whatever you want to, regardless of whether its correct or not. You have the freedom to disagree, but not to censor in public discourse.

Free speech is why we had websites like timecube.com https://en.m.wikipedia.org/wiki/Time_Cube

I don't agree with it any more than any other reasonable person, but the right to say and disseminate the information is there. You can't selectively ignore it because you don't agree.
