This chapter analyses constitutional intolerance on the basis of the Hungarian Church Law of 2011, which deregistered hundreds of religious organisations, attached special conditions to re-registration, and privileged a number of politically favoured religious organisations in return for their political legitimation and support. These micro-legal actions are analysed within the context of the notion of the “System of National Cooperation” and “constitutional identity”. Constitutional intolerance in Hungary appears to stem from a traditionalist commitment to protect traditional values: on the one hand, by strengthening the position of the main Hungarian churches, and on the other hand, by championing anti-liberal policies on gender and sexuality, including the prohibition from exposing minors to “gay propaganda”. But the varnish of Christianity is relatively thin: Hungarian society is thoroughly secularised with low numbers of church attendance, with language and ethnicity taking precedence over religion in their importance to national identity.
