The Czech writer Milan Kundera, in his book The Unbearable Lightness of Being (1984), defined it as "the absolute denial of shit". He wrote that kitsch functions by excluding from view everything that humans find difficult with which to come to terms, offering instead a sanitized view of the world, in which "all answers are given in advance and preclude any questions".

In its desire to paper over the complexities and contradictions of real life, kitsch, Kundera suggested, is intimately linked with totalitarianism. In a healthy democracy, diverse interest groups compete and negotiate with one another to produce a generally acceptable consensus; by contrast, "everything that infringes on kitsch," including individualism, doubt, and irony, "must be banished for life" in order for kitsch to survive. Therefore, Kundera wrote, "Whenever a single political movement corners power we find ourselves in the realm of totalitarian kitsch."

For Kundera, "Kitsch causes two tears to flow in quick succession. The first tear says: How nice to see children running on the grass! The second tear says: How nice to be moved, together with all mankind, by children running on the grass! It is the second tear that makes kitsch kitsch."
