Europe (which could mean anything from the UK to Belgium to Hungary to Turkey) never had absolute freedom of speech like the US. But yes, even by the US standards to champion freedom of speech, it is in retreat.
never had absolute freedom of speech like the US, which itself (since it was colonised) never had absolute freedom of speech.
EU Charter of Fundamental Rights, Article 11:
Freedom of expression and information
1. Everyone has the right to freedom of expression. This right shall include freedom to hold opinions and to receive and impart information and ideas without interference by public authority and regardless of frontiers.
2. The freedom and pluralism of the media shall be respected.
I got the impression that free speech in the US is limited to right to annoy people and harass politicians from distance. Seems to be more restricted than Europe actually since access is tied to private property and its culturally acceptable to remove people from private spaces if you don't like their speech. In this particular case the US embassy appears to have "hacked" their way by claiming that those journalists are a threat but if it was in US they could have been removed and have their free speech in a designated area simply because they don't want them there.
You can give finger to Trump from distance but you can't attend to his press conference to actually ask him stuff if he doesn't like you. That's just slightly different from Turkey where you will be arrested for giving the finger to Erdogan's motorcade(happened a few times, then Turks learned their lessons and in the stats Turkey doesn't arrest as much as Britain).
In contrast, in most of Europe you usually can approach and ask politicians whatever you like.
I'm saying this with love, so hear me out: Turkey has nothing to do with what comes to mind when you talk about anything European, except maybe some parts of Istanbul and Izmir.
I was born and raised in Turkey, and I have been living in Germany for nearly two decades, and I have Greeks, Bulgarians and Kurdish in my family too (no. I don't take pills to survive), so I know what I'm talking about.
It's not about inferiority/superiority, it's just a completely, unmistakably different culture, perspective on life, degree of pragmatism, and... everything. Especially when it comes to the topic at hand, freedom of speech. I think the Ottomans have a lasting effect there. The Turkish search for the new sultan never ends. You may say that some tendency in dictatorship exists everywhere, but in Turkey, you'll see authoritarian ambitions in the speeches of even the most supposedly liberal people.
I also have to say, I'm not even talking about religion. Perhaps the most religious groups, Muslim or Christian or Jewish, are the groups with the most similarities actually.
