Ľuboš Blaha (born 7 December 1979) is a Slovak politician, academic, post-Marxist philosopher and political scientist.

He continued his studies at the Comenius University in Bratislava (majoring in philosophy) From 2004 to 2006, Blaha worked for the Communist Party of Slovakia as the Head of its International Department.

[8] He argues that in the era of neoliberal globalization, the Left must be more focused on socio-economic (redistribution of wealth, cooperative ownership, economic democracy) rather than cultural issues and that the social conservatism of working class in Slovakia must be accommodated.

[10] His opinions are inspired by the school of international political realism (e.g. the ideas of Kenneth Waltz and John Mearsheimer) and neo-Marxism (especially William I. Robinson, Immanuel Wallerstein and Antonio Negri).

[19] In the 2016 election campaign, he expressed disenchantment with the EU and stressed the four issues which he sees as the main failures of Europe: Greece, Russia, TTIP and the migration crisis.

[21] During the Greek crisis in 2015, he openly supported Syriza and defended the arguments of Alexis Tsipras and Yanis Varoufakis.

[23] His arguments were 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, he claimed, would only favor fascists and the political far-right).

He has criticized "bleeding-heart liberals" for their supposed contempt for the people who are afraid of uncontrolled migration, calling them "racists" and "xenophobes".

[33][34] In July 2020, Blaha was investigated by the Police Corps under the law that prohibits denying or approving genocide or crimes against humanity.

[36] He has been repeatedly criticized for spreading hoaxes, conspiracy theories and disinformation through Facebook posts in which he attacks President Zuzana Čaputová, government politicians, several media outlets, the third sector, the Slovak Republic's foreign policy, the vaccination against COVID-19, and spreads pro-Russian disinformation narratives.

[37] However, Blaha refused to resign by saying the Academy could burn him to death, imprison and persecute him, but he will not give up his freedom of speech.
