I would agree if I hadn't had such a vast array of experience trying to counter misinformation in my online interactions with others already. I blame the bullshit asymmetry principle, aka Brandolini's Law.

Edit: This could be as simple as something that someone heard once and genuinely believes, passing on old wives' tales. Trying to combat a dedicated disinformation adversary is even more difficult.

Right speech is only a natural outcome of free speech if you have a very disciplined population. (Disciplined intellectually, morally, perhaps other ways as well.) Without that... not so much.

So, do we have that kind of population? Examine the empirical evidence. Do we?

I'm not in favor of censorship, but your position here doesn't work.

Dictating "truth" leads to 3 diseases.

1. People get stressed out.

2. People clutch their favorite bullshit in an unbreakable deathgrip.

3. People dictate their bullshit to everybody within earshot.

OTOH, truth tastes better than bullshit. Clearly. Given the freedom to experiment people will come around eventually.

So let's provide the people that freedom.
