[5] Cernea published in 2007 a book of essays and articles named "Manifest împotriva becalizării României" (A Manifest Against the Becalization of Romania), in which he argues that the "Becalization" (derived from the name of Gigi Becali, a nationalist politician who stresses his allegiance to the Romanian Orthodox Church) is threatening the values of an open society.

[9] His 2009 electoral platform was based on 10 points which he details on his blog and include: supporting conciliation and dialog within the Romanian society, supporting human rights and fight against discrimination, closer ties with Romania's neighbours, supporting green technologies, sustainable development, and green agriculture, increase in funding for education and research to 10% of the Romanian GDP, freer election system that is more fair to smaller parties, full separation of church and state and a national dialog on social issues such as legalization of prostitution, the problem of drugs and the recognition of heterosexual and homosexual civil unions.

[4] Cernea announced his intention to run as a Green Party candidate in the January 17, 2010 by-election for the Romanian Chamber of Deputies seat (in the Sector 1 of Bucharest), vacated after the appointment of Bogdan Olteanu as deputy governor of the National Bank,[11] however, the Bucharest Central Municipal Bureau rejected his candidature, because he is not a member of a parliamentary party, as the law requires in case of a by-election.

After the place was hallowed, Cernea, who was studying philosophy at the University, together with three other students, wrote a letter of protest, organized a conference about the subject and gathered 150 signatures against the building of the church.

[29] Cernea's association supported his case for the removal of icons from schools, arguing that the religious symbols represent a discrimination against non-Orthodox children and an infringement against the neutrality of the state.

The government of Romania originally wanted the cathedral to be built it in the place of Carol Park, but following protests, including those organized by the Solidarity for Freedom of Conscience Association,[32] it changed the plans.

Finally, in 2007, the state gave the Orthodox Church about 11 hectares of land in central Bucharest, next to the Palace of the Parliament and it promised it will pay partly the construction costs.

[34] Cernea argues that the current curriculum lacks the scientific and philosophical points of view, but in the same time, in religion classes, the seven-day creationism is taught, distorting the children's understanding of how the world came into being.

[35] In February 2008, his association asked the Ministry of Education to re-introduce explicitly the theory of evolution in the biology curriculum, arguing that Romania is the only European country in which it is not studied in detail[36] and organized a protest in front of the headquarters of the Ministry of Education for the reintroduction of evolution in the curriculum.

[39] In May 2007, he organized a small-scale protest against president Traian Băsescu's racist and sexist affirmations,[40] and in August 2007, the association argued against the practice at the national radio station of beginning the programme with a reading of Lord's Prayer.

[41] In August 2009, he protested against a law project made by the Romanian Government, which would have increased the number of signatures needed for running in the presidential elections to 500,000 and also required a €300,000 sum to be paid as a bail, only to be returned if the candidate gets a certain percentage.

[42] In May 2010, Remus Cernea is taking part, along with other high-ranking members from the Green Party (PV) at the GayFest, the annual gay pride festival of Bucharest.

[43] Remus Cernea declared that he will candidate for the forthcoming 2024 Romanian presidential election in an effort to counteract the political extremism in Romania.
