The European Union is founded on values of "respect for human dignity, freedom, democracy, equality, the rule of law and respect for human rights, including the rights of persons belonging to minorities". Those values are under threat from several of its members. In Spain, the government has unleashed state violence against those who peacefully advocate secession. In Italy, the government wants to deport Roma, an ethnic minority who were targeted for extermination by the Nazis. And in Hungary, the racist government has just made it illegal for lawyers and NGOs to help refugees claim asylum.
These actions clearly contravene the EU's fundamental values. They may also explicitly contravene European law and the European Convention on Human Rights, and look likely to result in court cases. But more than that, they require political action from other EU nations to enforce the Eu's values. These are not things civilised, democratic countries which respect human rights should be doing. And insofar as a government by its actions consistently fails to meet that standard, the EU should be looking at suspending or even revoking membership. If Hungary and Italy want to go back to being 30's racist shitholes, then they can do it without belonging to the EU.
