Former Slovak Prime Minister
Iveta Radičová said that if the referendum passes, "It will not improve the standing of families and marriages; and there won’t be any more children, either." She criticised the referendum as being pushed by people who want to "want to cover up the real problems" in Slovakia, like "balancing of work responsibilities with childcare, unemployment," financial insecurity and domestic violence. Radičová described the movement as motivated by "the fear of the new, the unknown, and the other" and condemned opposition to
sex education, pointing out that it is proven to reduce sexually transmitted diseases, unwanted pregnancies, and delay sexual experimentation. The libertarian party
Freedom and Solidarity criticised the referendum,
Amnesty International has condemned the country's discrimination against LGBTQ people and the international media, including
The Economist, critiqued the political process in the country. Gay rights groups criticised the referendum, saying "unemployment, social problems and alcoholism" would not be solved by a vote to ban gay marriages or adoptions. International critics criticised the ruling
social democratic party for pandering to populist religious homophobia, and critiqued the ballot as a waste of millions of euros, and a distraction from Slovakia's economic woes, and "genuine problems of Slovak public policy."
Pope Francis supported the referendum, blessing the opponents of gay rights, stating “I greet the pilgrims from Slovakia and, through them, I wish to express my appreciation to the entire Slovak church, encouraging everyone to continue their efforts in defense of the family, the vital cell of society.” A group of theologians issued a position paper claiming that the referendum is touching on ethical questions and those should be solved by discussion rather than by voting. The authors of the position Ondrej Prostredník, František Ábel and Igor Kišš, all from the Lutheran Theological Faculty of Comenius University in Bratislava also claimed that several times in history the way of shortcuts and authoritarian decisions in favor of Christian values proved to be bad and damaged the very cause of Christ's Gospel. They also criticized the referendum as an immoral attempt to shift the responsibility for the crisis of family values in the Slovak society to homosexuals. The position paper as joined by 48 theologians and intellectuals from different churches and sectors of the society. Another EU nation, Croatia, banned same-sex marriages in a
constitutional referendum on 1 December 2013. Turnout in Croatia was also less than 50%, but its constitution does not invalidate a referendum based on turnout. ==Opinion polls==
