Really? 27% of Germans support the right to speech that offends minority groups, and less than half of Europeans as a whole [0]. A Swedish man was convicted for producing art that was deemed racist, and the owner of the gallery that displayed it was fined [1]. A man was famously prosecuted for a video of a dog performing a nazi salute [2]. A refugee may be expelled from Denmark after he left comments "celebrating" the Charlie Hebdo attacks [3]. I'm not saying these excuse things America has done, but you saying that Europe is the last place where liberty is valued is patently ridiculous.
