We are talking about an adult audience, right? They are allowed to vote. So you have to assume they are independent enough to make their own decisions. Period. Your argument for censorship sounds a lot like patronisation.
It is not patronising to say that people are not all created with the same set of skills, beliefs, and values, and that some will engage with obvious bullshit. Many are not capable or interested in engaging with complex topics in a way that does not self-reinforce their pre-existing opinions. I have discussed this elsewhere[0].
When a group of people are motivated to exploit the weaknesses of others in order to get them to do things that are damaging to our democratic institutions, and they use misinformation to do it, it is unpleasant but not unreasonable to me to suggest that spreading lies through misinformation is as serious as suppressing truth through censorship and that they should both be treated equally seriously.
If you want to drive a car, you have to proof you are able to do so. Why not demand the same if you want to vote?
Another way to see this is that those with less education or influence are basically the new women. The argument against giving women the right to vote was basically based on the same viewpoint. They dont know about the world, so all they can do is harm if allowed to vote.
> If you want to drive a car, you have to proof you are able to do so. Why not demand the same if you want to vote?
Not sure if you meant this as a rhetorical question, an ironic one, or a real suggestion about creating restrictions around who can vote.
Either way, "free speech is a thing of the past" is a bit all-or-nothing. It's always been a battle, never as good as we thought it was (such as the argument Noam Chomsky makes in 'Manufacturing Consent'), and always been tricky to figure out what to do when, and where.
But it's not a thing of the past.
