The most common argument for censorship appears to be protecting people from harmful information. I have found that this harmful information is more likely to be the truth. Even if we assume the censored information is lies, it is still better it is exposed than hidden. Lies can be questioned and disproven. It is better that we known what is false or malicious than for it to be hidden away.
I understand why people turn to other people for advice regarding information. Most of us are brought up to rely on someone else to guide us about what is true and what is false. Even when we are older, we often seek some form of mentor. This is OK as long as we still question things for ourselves and do not become overly dependent on any one person or group of people.
This is how government and other agencies tends to keep people in the dark and dillusional. I basically think that we humans understands what's good and bad. We can sieve between harmful and non-hazardous information, we just need the luxury of exposure.
This was really enlightening, I was inspired.
