The problem isn't freedom of speech, it's people using conformation bias, or people being incredibly dishonest for a narrative. We can't fix that even if we censor speech. So really censorship wouldn't help.
There are people who are so fucking dumb, I mean monumentally fucking stupid, that think the earth is flat, for over 2000 years we can prove it's not. What good does a law make? I'm honestly hot under the collar people are that fucking brain dead and cultish. Yes, it rustles me. But I have scientific proof from this very moment going back to Greek days saying you are wrong.
To outlaw or stop it gives it a new power. In some cases it can get literally dangerous vs funny and or offensive, like anti vax. But then it's one thing to think vaxes are bad, vs take an action about it. Let's be real if you don't have kids or won't/can't. It really doesn't matter nor do you have ability to do anything other than well sound silly.
Again, you want to use cherry picked data that fits what you want.... this can apply to anything. Nature of science and statistics, you can "prove" anything, but when you take it to a real testing ground or debate we know what's real and what isn't.
Some things do bother me, but I know what makes me most upset and or baffled I as a layman can utterly destroy in a debate. When you act like an adult, and beat someone in a debate, you look good as does your cause. We can't stop kooks who think the moon is a projected image, so why worry?
My biggest scare is how we are educating people to step away from the basic rule of thought, facts win. I think freedom should be just that not have some limits and I am scared to death what if the shoe changes feet? What if, we lived where people like Lindsay from QKS was in charge? I'd go to prison for saying pedo's are bad. There's untold amounts of information showing this. But these people are trying to brush the facts aside, and not even replace with cherry picked ones, but with it feels right or ok.
The fact so many groups be it schools governments, companies allowing simple facts to be replaced is the real fear and worry as once that's done not only will civil debate end, the stop of "right think" will be enforced and I don't mean the politcal spectrum, I mean basic functions of the world that upset some nutter will be stopped.
I don't want to live in a world where calling the moon landing real is an imprisonable offense, nor do I want to live in one denying it is.
