Europe is a continent of diasporas[1], that should make it much easier to accept refugees but sadly people don't seem to think much about it. Also, most people in Europe will know someone or someone's family member who had to leave the country due to wars and persecutions. For example, my grandfather was tortured by it's own country's state police back in the 60s. Most people in Europe know stories like his.
