The right to lie is fundamental to the principle of freedom of speech. Also the lies you think are “obvious” are almost certainly not obvious to everyone - they rarely are. And if someone cannot share a different view then you can’t arrive at the truth.
It's obviously not. We prosecute fraud. No freedom can be absolute unless it is singular.
We can. But we don't and never have. Anyone arguing for the freedom to lie without consequence is off the deep end. There has never been a society that doesn't punish lying and fraud. (What constitutes a lie is a deeper question.)
> even if you think something is a ‘truth’, what you perceive as a ‘lie’ must be allowed
Why? Also, where? Ever?
If I go and commit a bunch of fraud, I'd expect--at best--riotious laughter from anyone with more than two brain cells if I offered, as my defence, that I cannot be punished for defrauding everyone because I'm part of the truth-finding process.
> truth that is just unchallenged feels more like propaganda
Propaganda is regularly challenged. A truth that cannot be challenged is an article of faith. This entire debate reeks of arguments from faith on both sides.
One, not true. If a real estate agent sells you a house based on a bunch of lies and somehow forgets to charge a commission, they're still punished.
Two, you're still drawing criteria per which speech is punished.
Let's edit the premise. No sale occurs. The agent spins some yarn, but you catch on and report them to a regulator. Do you expect them to go unpunished simply because it was all talk? Should they?
