That is currently irrelevant to this discussion as most countries EXCEPT apparently Greece have no laws against "heresy".
Where did you get that? Heresy is also a crime in Germany, for instance. There are also several other kinds of opinions that can get you in prison if you say them aloud in Germany. And people get even indicted and convicted for heresy and other forms of illegal speech every now and then. And no, it is not only Germany and Greece that do not "respect" free speech.
So the conclusion is that EU respects free speech, but Greece does not.
The fact is that the concept of free speech simply does not exist as an "inalienable right" the way it does in the US.
The EU has no respect for free speech whatsoever. These days, you can even be thrown into jail for heresy against God, even if heresy is not a crime in the EU state you live in:

Graffiti is art about as much as rap lyrics are poetry. There is a tendency in certain egalitarian circles to call absolutely anything art that wants to be (and also a lot that doesn't), but if everything is art, the term has no meaning anymore, and the attempt to elevate something by calling it art although it obviously isn't only results in dragging everything that actually is art down into the dirt. Sadly, that seems to be just as well to those egalitarians.
