Since I have researched the topic quite a bit, but failed to find satisfying answer that I was looking for, I will ask it here. I think my question opens at least, very interesting debate. In 2014 there was a case, where a man in Slovenia(EU) posted a message regarding some local handball match to his group Facebook wall, which stated "The police intervened only at the end of the match... Typical for these clowns". The man was charged with insulting law enforcement and fined 105 Euros (by law enforcement). The original source is here (translated using google translate): https://goo.gl/Y9kELs
My question: If some statement that is posted on Facebook by non-American citizen, and the statement is subject to, for instance hate-speech laws in country of the person that posted it, isn't the person protected by the first amendment given the fact - that let's assume the post that was made is hosted on American server, which protects free speech under first amendment law. So if we expand this, he made a statement technically speaking in USA.
