Yeah, and? You think those things shouldn't' be available?

If someone does police work on those things, should that information not be available to the public as it inform the public?

You are basically claiming some forms of knowledge are too dangerous for people to know. Also, as soon as you start dictating what is 'misinformation' you are creating the problem where knowledge and truth are defined by a central authority, which comes with it's own systematic problems. The people in power of these censorship could easily decide that anti-Nazi rhetoric is misinformation as much as they could decide that Nazi-rehtoric is.

There is no free lunch. Information is free and it's dangerous, or it's suppressed, and that's dangerous as well.

I am a former teacher and academic. I taught philosophy, and plenty of people I have met think philosophy is evil and hateful and terrible and shouldn't exist. I think it's great and wonderful. Which of us should have our views censored and suppressed? Socrates was viewed as spreading misinformation, and sentenced to death for it. Do you think his works are misinformation?
