> An idea not being acted upon is not dangerous. A gun not being fired is not dangerous. A deadly virus that is contained is not dangerous. Ideas are seeds; action is impossible without them. All you're doing is pushing the responsibility one step further; instead of preventing the spread of ideas we have to prevent their effects. Now instead of dealing with the cause, we have to deal with the symptoms. A meme like "immigrants are the source of all our problems" is a dangerous idea, because of the actions it can directly cause. Preventing its spread is just good mental hygiene. Cults are another place where ideas are most certainly dangerous; but this time for the individual. So is any religion/ideology people are willing to die for. Most ideas are not dangerous. Also, I might be completely wrong; if I lived in Galileo's time, I might be claiming heliocentricity is a dangerous idea.
