> Expulsion of Jews from Spain [...] On 31 March 1492, the Catholic Monarchs of Spain, King Ferdinand II of Aragon and Queen Isabella I of Castile, issued the Alhambra Decree, ordering all unconverted Jews to leave their kingdoms and territories by the end of July that year, unless they converted to Christianity
Someone correct me if I'm wrong, but we (I live in Spain) have come a long way since 1492 (534 years ago) and if that's the most recent example you can find of "Europe's treatment of perceived outsiders" I think you yourself know that stuff like that doesn't happen today, in Europe.
