In his speech, the pope said millions of people are being forced to flee their homelands due to "conflict, natural disasters, persecution, climate change, violence, extreme poverty, and inhuman living conditions." They're forced to flee. These are the people that become refugees and migrants. Pope Francis remarked that "indifference fueled by populist rhetoric in today's world, fans the flames of rejection that threaten the rights and dignity of migrants and refugees. Faced with this kind of rejection, rooted ultimately in self-centeredness and amplified by populist demagoguery, what is needed is a change of attitude to overcome indifference and to counter fears with a generous approach of welcoming those who knock at our doors."

Pope Francis is being too nice.  Instead of saying "populist" he should use the term used in the 1930s: fascism.
