Be well warned - the stuff happening on reddit, the tools being developed by moderators are the epitome of the road to hell being paved with good intentions.
The old generalized ideological position of Free Speech is no longer tenable, whether we like it or not.
I'm a proponent of Free Speech, and I've spent the time to understand why its important, and why Humanity has valued it and argued for it.
The ideas behind it are sound.
It falls flat when having to deal with the modern internet.
In the simplest explanation - Free Speech was NEVER designed to deal with things like channel saturation and specialized targeting of the human hind brain which happens today.
The Free speech model is the bazaar of ideas model. Everyone can see all ideas, and decide for themselves what is best. Heinous ideas are important because at the very least - people can define themselves against it.
Modern impediments to free speech arise because small groups of humans have new abilities to disrupt the bazaar.
They can spam a single message, they can overwhelm normal discourse, and we have learnt that emotion over comes reason regularly. That's how the brain is designed.
In the same way environmental rules are made to prevent abuse of the commons, or pollution of common land, rules will be made to "protect" free speech.
How those conflicting ideas will be meshed, is beyond me.
Without such rules, motivated people can and will abuse/spam the shit out of a communication channel in order to take control of it.
fundamentally - the human brain itself is un-prepared for this environment.
Therefore, rules will be made to ensure that the human brain is not completely harmed by it.
