If you censor people. How will you know how they think? What if someone you are standing next to is someone you don't want to be standing next to but you have no idea because anytime they spoke they were censored? You wouldn't know they might be dangerous or a bad person simply because you are never permitted to hear them speak.
That is just one reason free speech must exist. People you don't like MUST be allowed to speak. Ideas that you don't like must be allowed to be open and available.
If you have the power over who is censored yet you happen to be a bad guy kind of like a Hitler, Mao, Stalin type. When you censor those who you disagree with you are not handling misinformation. You are simply not allowing good ideas to be heard. Your hope is that if the people can't hear the ideas then they will blindly agree with what you tell them to believe because that is all they can hear.
If your ideas cannot overtime withstand the challenges targeting them then your idea failed.
It is like an evolutionary process for ideas. It is also how the scientific method is supposed to work.
Anything can be challenged. That doesn't mean the challenger is correct. Each challenge must be met with words, and proof.
Censoring short circuits this process...
It makes certain ideas unable to be challenged. It also makes it so ideas cannot even be heard to be challenged.
Censorship and banning do not work and they always lead to tyranny and authoritarianism.
If the censors happen to be blocking all of the people you don't like and things you think are bad that doesn't make them GOOD. In fact, if you cheer for them it makes you a bad guy.
If you don't like something. Challenge it. Yet never censor it.
If you don't think you can effectively challenge it then discuss it with other people and perhaps if it deserves to be challenged you will find an ally who can.
If you still cannot then there is still one really cool thing about freedom. You can choose not to listen to it. You can choose to think it is false.
No one stops you from making those decisions yourself.
When someone censors they are assuming they have the right to dictate what other people are allowed to hear, say, etc. They are taking the decisions away from you. The keyword there was "dictate". You do realize that is where the word Dictatorship comes from... maybe you didn't.
Slavery is safe in that someone else makes your decisions for you. You are not responsible for the work you do. You were forced to do it.
Freedom is risky. You are responsible for your own choices.
There is a big push for more and more aspects of slavery to be the norm for society.
I accept the risk.
