Blaha opposed mandatory quota proposals during migration crisis. His arguments are based on human rights (not forcing refugees to be settled in countries in which they do not want to live), on tactical thinking (Central European societies are not ready for shock solutions, they need time and sensitive approach), and on political realism (mandatory quotas in these societies would only favor fascists and the political far-right). He has criticized "bleeding-heart liberals" for their contempt of the people who are afraid of uncontrolled migration, calling them "racists" and "xenophobes". However, he strongly refuses and condemns islamophobia and advocates for the solidarity of Slovakia with the EU, be it material, financial or personal.
