Stephen Castles places the blame for anti-immigrant sentiment on extreme-right political parties. True False

False. While Castles acknowledges that extreme-right parties exploit and amplify anti-immigrant sentiment, he argues that the roots are more complex and lie in broader social and economic anxieties, including globalization, economic restructuring, and perceived competition for resources and jobs. He doesn't place the *blame* solely on these parties, but rather sees them as one factor among many.
