As your previous source said, not having health insurance is illegal in France. We're a far cry from your original "saying that you don't need health insurance". You can say that as much as you want. You just can't push other people to put themselves in an illegal situation.
> If it is not limitation of freedom of speech, I think it is very close.
[Translated context: It would become illegal to falsify facts about the consequences of abortion]
I want to be very clear: The american concept of "Freedom of speech" does not exist in most of Europe. In most of the world outside of the US in fact. It's even a stretch to say it exists in the US.
When people think "limitations on freedom of speech" they immediately think China and Iran. But in the US, I can't threaten the president (or people in general, but nobody's gonna jail me for that). I can't yell "Fire!" in a crowded theater. I could give you a lot of american examples which are far more grey area than what you've given me in these sources. The US has these limitations, generally for public safety.
In the context of a US-centric forum, claiming that "you can get jailed for speaking against abortions" is abhorrent because the US is still at the stage where abortions are not considered a fundamental right, and there is an ongoing debate about it. Therefore, you think "well, then, half the US would go to jail".
In the context of a country that does have a framework around abortion, that does make it a fundamental right and where it's essentially a non-issue... then it's a lot easier to see why it's illegal to publish false information about it.
This is a country where gays and muslims are treated with respect, where women's rights are respected and where public health is highly valued. In that context, these restrictions are, like american ones, a matter of public safety.
